Thrust needle roller bearings are often found in gearsets mounted between gears, and the housing and the rotating shafts in an automatic transmission. The location of where a bearing is to be mounted largely determines what type of bearing will be used. Customers also prefer bearings in a unitized design, which facilitates greater ease of handling and installation. However, unitized bearing assemblies must allow for some eccentricity during operation, such as that which is found in a torque converter. Here, challenges exist in regards to preventing excessive wear and fatigue failure of the cage. To resolve such issues, we applied two measures: 1. Improve wear-resistance and fatigue-strength using a special heat treatment process applied to the cage; and 2. Expand bearing internal clearance of thrust needle roller bearings fitted with raceway ring that has a curved lip along the entire outer circumference. This report introduces NSK's thrust needle roller bearing matched to a wear-resistant and high-strength cage (NSK HYTEC Bearing) for use in eccentric (off-centering) applications.

Chuang Hon Yi Axle Co.,Ltd. offers a broad selection of needle bearing designs, from machined-race bearings to track rollers, thrust bearings and combined axial/radial bearings. These are generally used for high-load applications requiring low to moderate speeds. These products are designed for specific applications requiring high load capacity within minimum space requirements. Design Attributes

Assemblies incorporating rollers or cam followers are manufactured in accordance with the requirements of the application, particularly in the case of flight controls.

Special design options include a wide range of geometries, clearances, seals, lubricants and performance features.

Self-aligning units and high-temperature capabilities are available.

Special steels – with surface treatments such as coating and plating with copper, chromium, silver and even gold – are used for specific operating conditions.

Applications

Airframe and landing systems

Mechanical accessories such as engine nozzle controls, helicopter rotor blade supports and various servo controls
