440C Stainless Hybrid Ceramic Ball Bearing With SI3N4 Ceramic Balls Rubber Seals
These bearings have ceramic balls, with stainless steel races & retainers and rubber shields. High Precision ABEC #7, Ceramic hybrids are lighter, Your best economical choice for Ceramic Hybrid fishing Reel bearings, capable of achieving higher RPM's and sustaining higher operating temperatures than traditional bearings.
Stainless steel is one of the most popular materials for use in bearing design, and modern stainless steels are renowned for their hard-wearing durability and improved anti-corrosive characteristics. For fishing reel , stainless steel is often the material of choice.Most of the range of fishing reel stainless stell bearins are available in 440 grade stainless steel.
Application of ceramic ball bearings:
1. Ceramic ball bearing has the characteristics of high temperature resistance, cold resistance, abrasion resistance, corrosion resistance and insulation, and can be used in extremely bad environment and special conditions.
2. Ceramic ball bearings can be widely used in aviation, spaceflight, navigation, petroleum, chemical industry, automobile, electronics, metallurgical, power, textile, pumps, medical equipment and scientific research.
Features of ceramic ball bearings:

Our hybrid ceramic bearings are available open or with PEEK seals. Some sizes may also be available flanged
The full ceramic ball bearings listed below are supplied with rings and balls made from zirconium dioxide (ZrO2). These zirconia bearings are available as full complement (no cage) or with cages made from PTFE, PEEK or 316 stainless steel.
These are non magnetic, non-conductive and highly corrosion resistant to most chemicals although ZrO2 bearings are not recommended for prolonged contact with steam. Full complement bearings or those with a 316 stainless cage can be used up to 400°C while bearings with a PEEK or PTFE cage can cope with temperatures of up to 250°C. For temperatures below -70°C, PTFE or 316 stainless steel cages are preferred. Standard radial clearance for full ceramic bearings is C0 but other clearances can be supplied to order.
ZrO2 ceramic bearings are generally used for their extreme temperature capabilities, excellent corrosion resistance or non-magnetic properties. Other sizes can be supplied on request.
