Bearing Description
What is Needle Roller Bearing?
A needle roller bearing is a special type of roller bearing which uses long, thin cylindrical rollers looking like sewing needles. Rollers of ordinary roller bearings are only slightly longer than their diameter, but needle rollers are at least 4 times longer than their diameter. Like all the other bearings, they are used to reduce the friction of rotating surface.
Compared to ball bearings and other conventional roller bearings, needle bearings have a larger surface area in contact with the raceways, so they can support a greater radial load but not axial load. They are also thinner, so they require less clearance between the axle and the surrounding structure.
Needle bearings are widely used in automobile components such as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel drive vehicle typically has at least 8 needle bearings (four in each U joint) and often more if it is particularly long, or operates on steep slopes.
Diverse types of needle bearings are available in a wide variety of sizes and tolerances, for a multitude of applications such as gearboxes, automotive power transmission systems, 2 and 4 stroke engines, planetary gear sets and air compressors.
Needle roller and cage assemblies are offered in single or double row, solid or split cage, metric and inch sizes. Single and double row bearings are available with or without ribs, and with or without inner rings.

Planetary Gearbox Components
The basic components of a planetary gearset are an input, output, and stationary position. Different types of planetary gearboxes will have different output ratios and torques. A leading company for planetary gearbox design, CZPT, provides the necessary components. These components can vary in both male and female shafts and come with a variety of modular options. Here are a few things to consider about each component.
CFHK Series
The CFHK Series is a multistage planetary gearbox that contains multiple planetary gears. The multiple teeth of each planetary gear mesh simultaneously during operation to increase the transmittable torque. The gears are case hardened and ground, and the ratios of the planetary gears are integers. They were first functionally described by Leonardo da Vinci in 1490. Today, the CFHK Series is a favorite among automotive engineers and manufacturers.
The CH Series offers high accuracy with a compact design and case hardened, hypoid, and helical gearing. These gearboxes are also available in the CFXR series, with low backlash and friction. These planetary gearboxes are designed to provide high torque and high precision in a variety of applications. In addition, the CFXR series features 100% helical gearing and low backlash.
The CFHK Series features a sun gear that drives the next stage. These gears can be put in series or serially in the same housing. In some cases, the output shaft of the first stage becomes the input shaft of the second stage. In addition, ring gears are also used as structural parts of smaller gearboxes. An example of a planetary gearbox is the pencil sharpener mechanism. The pencil is placed on an axis that is set on a sun gear. The sun gear drives the next planet stage.
A planetary gear unit’s gear ratio is determined by the number of teeth in the sun gear and ring gear. The smaller the sun gear, the smaller the ratio between the sun gear and planet gears. The largest gear ratio in a planetary gear unit is 10:1. A higher number of teeth increases the transmission ratio. In order to maximize torque, the planetary gears must be rearranged. A smaller sun gear will have higher torque than a large ring gear.
CFX Series
The HPN Harmonic Planetary(r) Series planetary gearboxes offer a low-cost solution with high-performance and high-reliability. This modular design is easy to install and requires very little maintenance. Its planetary design and full complement of needle rollers allow for extended life and quiet operation. In addition, the HPN Harmonic Planetary(r) Series is available in a range of sizes.
The compact size and high-speed design of planetary gearboxes results in excellent heat dissipation. However, high-speed or sustained performance applications may require lubricants. A planetary gearbox will have smaller minimum steps to minimize noise and vibration. Planetary gears will give you the highest level of efficiency while minimizing noise. As a result, they can provide high-quality 3D prints.
A planetary gear train is composed of a ring gear and planet gears, each supported by a carrier. A ring gear is pink, while the sun gear is red. The sun gear and carrier rotate around each other at a 45-degree angle. This is also known as an epicyclic gear. Planetary gearboxes are often found in space-constrained applications. The CFX Series features a compact design and excellent performance.
The CFX Series features a robust design that is easy to install. Its compact size makes installation of planetary gearboxes easier and faster. They are available in 3 different configurations for continuous, intermittent, and counter-clockwise operation. The CFX Series offers the perfect solution for your accelerating needs. They’re a great solution for any automotive or industrial application. You can easily configure the CFX Series to meet your specific requirements.
CAP Series
The Candy Controls CAP Series is a new generation of compact, precision planetary gearboxes that combine high torques with low backlash and exceptional wear resistance. This rotary flange planetary gearbox is ideal for a variety of industrial, mining and marine applications. Its modular construction enables users to easily mount different stages, hydraulic or electric motors, and different types of gears. Its CPH Series features an extremely rigid alloy steel housing, carburized gears, and induction hardened gears.
The CAP Series utilizes multiple planetary gears for high torque transmission. The number of planetary gears is not fixed, but most planetary gearboxes utilize at least three. The larger the number of planetary gears, the higher the transmittable torque. A planetary gearbox is composed of multiple planetary gears with a meshing action that occurs simultaneously during operation. The result is a higher efficiency and a smoother, quieter operation than a conventional gearbox.
The VersaPlanetary range features modular design for easy installation. This system includes mounting plates for typical FIRST (r) Robotics Competition motors. The mounting plates are designed to fit each motor. These planetary gearboxes are compatible with various types of motors, from small electric motors to large, heavy duty ones. They are also compatible with a variety of mounting systems, including CIM motors.

The CAPK Series features an array of high-quality, innovative features.
CZPT SMART Lubrication technology is used to keep the gears well-lubricated and reduce noise and vibration. The planetary gearbox’s 3-gear design is ideal for DIY CNC robotics. This series has a long history of quality, and CZPT uses only the best components. The CZPT 3:1 High Precision Planetary Gearbox is an excellent choice for CNC Robotics and other applications.
A multi-stage planetary gearbox combines individual ratios for a greater number of ratios. Additional planetary gears increase the transmittable torque. The direction of the output and drive shaft are always identical. The CAPK Series features a high-quality, durable construction. They are made from stainless steel and offer a long-term warranty. They are the best choice for industrial and commercial applications. While planetary gears are more expensive, they are highly efficient.
CFH Series
The Candy CFH Series planetary gearboxes offer the benefits of a modular design and a low backlash. They offer a variety of size options and excellent durability. This planetary gearbox is compact and wear resistant. The CFH Series planetary gearbox has a carburized, induction hardened gears and a rigid alloy steel housing. Its low backlash and precision make it an excellent choice for industrial applications.
The CFH Series planetary gearbox is a highly efficient, high-speed helical gear. The compact design of this gearbox results in high heat dissipation and low mass inertia. Planet carrier bearings experience significant lateral forces from the transmission of torque. As a result, radial and axial forces oppose each other. The result is that the torque is distributed over 3 gears, reducing noise, vibration, and wear.
The planetary gearbox has 3 main components: a sun gear (also known as the input gear), a ring gear, and 2 planet gears. These are connected by a carrier that rotates about a 45-degree clockwise axis. The CFH Series of gears is available in triple and double stages. They can also be used in electric motors. As a result, the CFH Series is highly versatile.
The CFH Series of planetary gearboxes can be found in all kinds of applications, including automotive transmissions. Their compact design and high-performance performance make them a popular choice for space-constrained applications. This gearbox has several benefits and is a great alternative to a conventional helical gearbox.
