China ceramic reel bearings Si3n4 fishing rod reel hybrid ceramic bearings
Material: AISI440C stainless steel races
Balls: Si3N4 ceramic balls
Size:4x10x4mm
Seals: Open/2RS
Ceramic Orange Seal Fishing Reel bearing kits are an upgrade replacement to stock fishing reel bearings. These ABEC #7 bearings have ceramic balls with stainless steel races and retainers. Orange Seal bearings have a non-contact rubber seal which allows the bearing to spin freely with out any excess drag. Ceramic will never corrode; it has less rolling resistance and is lighter and than steel. As a result ceramic bearings last longer and cast longer. All Ceramic Orange Seal fishing reel bearings are supplied Cleaned of Oil or Grease and Lube Dry.

Versions of miniature ball bearings
-
Single row
-
Main dimensions according to DIN 625-1. Inside diameter below 10 mm. Economical "all-round bearing". Versatile.
-
Miniature flanged housing units
-
For simplified locating bores in which the bearing is supposed to be axially fixed. Inside diameter below 10 mm.
-
Full complement ball set
-
Without a cage and maximum number of balls, higher load carrying capacity than caged miniature ball bearings of the same size.
Material description of miniature ball bearings
-
Miniature ball bearings made of rolling bearing steel
-
are extremely economical, withstand extremely high load-ratings and are suitable for temperatures from circa -10°C up to +120°C, in case of rubber seals up to circa +100°C in the long run. The rolling bearing steel is wear-resistant, shock-resistant, conductive and magnetic.
-
Miniature ball bearings made of stainless steel
-
are hygienic, corrosion-resistant, lubricated with grease for the food industry, offer high load-ratings, magnetic and are admissible for a temperature range from circa -20°C up to +120°C, in case of rubber seals up to circa +100°C in the long run.
-
Hybrid bearings with ceramic balls and rings made of stainless steel or rolling bearing steel
-
are subject to a lesser wear and tear compared to bearings of similar size with steel balls. The ceramic balls are current insulating - optimally for use in engines and generators. Hybrid bearings are lighter than bearings with steel balls of the same size, withstand higher speeds and operate in a temperature range from circa -20°C up to +130°C, in case of rubber seals up to circa +100°C in the long run. Hybrid bearings are magnetic.
-
Miniature ball bearings made of ceramic
-
are extremely wear-resistant by their great hardness, corrosion-resistant and durable. They have good emergency running characteristics, are lighter than steel bearings of the same size, suitable for dry run, current insulating, non-magnetic, withstand extremely high speeds. Bearinngs with cages made of PTFE operate up to a temperature of circa +160°C, bearings with cages made of PEEK up to a temperature of circa +160°C.
