Insulated Bearing 6336 M/C3VL2071 For Electrical Motor

Bearings in electric motors and generators must support the rotor radially and locate it axially in relation to the stator. The typical bearing system consists of a locating and a non locating bearing. In most medium and large motors and generators, the locating bearing is a deep groove ball bearing, while the non-locating bearing can be a deep groove ball bearing, an N or NU design cylindrical roller bearing or a CARB toroidal roller bearing. Smaller motors, fitted with two deep groove ball bearings mounted on a short shaft, often have a cross-locating bearing system.

Electrically Insulated Bearing 6336 M/C3VL2071 is Deep Groove Ball Bearing design. its dimension is 180×380×75mm, it has the same dimension and the same design with normal chrome steel 6336 M bearing. but the most different is 6336-M-J20AA bearing with Aluminium Oxide Coating. the coating can Electrical Resistance Voltages up to 3000 V DC. This kind of bearing are widely used in high quality demand application like traction motor.

Most motors are designed with a locating/ non-locating bearing system. The locating  bearing positions the shaft axially. The non locating bearing is designed to accommodate  thermal elongation of the shaft to avoid  induced axial loads. For the locating bearing position, radial  bearings that can accommodate combined  (radial and axial) loads are used. These  include deep groove ball bearings, matched  single row angular contact ball bearings, double row angular contact ball bearings and spherical roller bearings. There are two ways to accommodate thermal displacements of the shaft at the nonlocating bearing position. 


The first is to use a  bearing that only accommodates radial loads  and enables axial displacement within the  bearing. These include CARB toroidal roller  bearings and those cylindrical roller bearings  that have one ring without flanges. The other method is to use a radial  bearing mounted with a loose fit in the housing so that the outer ring  is free to move axially

Different application requirements need to  be considered when designing an electric motor’s bearing system such as service life, noise levels and maintenance. Sometimes, the requirements are such that a compromise may be necessary. For example, if an application has high operating temperatures, it may not be possible to use greased-for-life bearings that have seals or shields. Instead, relubrication features may be necessary.


Features of Electrically insulated bearings

1. High insulation properties

To prevent electric corrosion in bearings, a highly productive aluminum ceramic coating material is used to coat the outer ring, and by combining optimized additives, insulation performance is improved by about tenfold.

2. Improved durability

· Optimizing bearing elements improves film impact resistance by a factor of 3x.

· Optimized ceramic coating materials makes for excellent heat dissipation.
