Product Detail

NACHI 6205-2NSE9 bearing Product description

This Nachi 6205-2NSE ball bearing is made of chrome bearing steel and has rubber seals. It has a 25 mm inside diameter, a 52 mm outside diameter, and a 15 mm depth. The bearing has deep groove geometry for supporting both radial and axial loads and high speeds.

The races are made of chrome bearing steel for durability and resistance to deformity under heavy loads. The C3 radial clearance allows thermal expansion for continuous operating temperatures up to 248 degrees F/120 degrees C.

Rubber seals on both sides of the bearing help retain lubricant and exclude contaminants. The ball is made of chrome bearing steel for strength and resistance to wear and deformation. The static load rating is 7,900 newtons and the dynamic load rating is 14,000 newtons.

A steel cage spaces the balls for even load distribution and prevents contact to reduce friction, vibration, and noise. The maximum speed with grease lubrication is 9,000 revolutions per minute (rpm). This deep groove ball bearing is used in applications such as electric motors, compressors, and material handling equipment, among others.

Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use.

The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.

 

The shield design was optimized using finite element analysis and dynamic analysis modeling techniques. The design profile and plate thickness provides rigidity that helps quiet operation as well as retain grease and protect against intrusion of major contamination.

Rings and balls made of select material have superbly controlled accuracy such as roundness, contour, surface finish, and hardness to provide quieter operation, reduced vibration levels, and long life. Rivet-type pressed steel cages for strength and durability. High-performance grease for long life and low noise.
