WOLEE Stainless Steel Ball Bearings - Resistant to corrosion and high temperature.

As performance level of precision machinery has risen, the range of applications using ball bearings has become broader, and the demand for higher performance and durability of ball bearings has increased. Industrial needs for ball bearings having high anti-corrosion technology and the ability to withstand fierce conditions while maintaining the preciseness of ball bearings originally required have also increased.

WOLEE stainless steel ball bearings are the products that comply with current industrial needs.

Special Features
1. High resistance to corrosion
2. High stability in high temperature (Higher available operating temperature by approximately 50 degrees C, or, 122 degrees F than normal bearing steel)
3. High resistance to chemicals

Materials
AISI 440C martensitic stainless steel is used for inner rings, outer rings and balls. AISI 304 austenitic stainless steel is used for retainers and metal shields. Standard material of rubber seals is nitrile butadiene rubber (NBR), and other materials such as fluorinated rubber, acrylic rubber, etc. are available upon request.

Enclosure Types
STANDARD SEAL

WOLEE  Bearings with suffix of 2RS are equipped with this type of seal. The seal is Nitrile Butadiene Rubber(NBR) molded round a flat metal ring which imparts flexibility and strength to the construction and helps to control sealing performance. The seal is compressed into a groove in the outer ring to ensure a tight joint without creating outer ring distortion.


STANDARD SHIELD
WOLEE  Bearings with suffix of ZZ are equipped with this type of shield, which is a formed metal disc, and is crimped into a shield groove in the outer ring, keeping a close running clearance with the inner ring. Shields help to retain grease lubricant and prevent the entry of chips or large particles into the bearing.
