Characteristics of B series Plastic (Ball) Bearings

PolyacetalAn engineering plastic with balanced mechanical strength properties, and it is excellent especially in fatigue, abrasion resistance, creep resistance, dimensional stability, self lubricity, heat resistance (continuous use at 105℃ or less), and chemical resistance.
High quality
High precision
Plastic bearings with the number one dimensional accuracy
Dimensional precision of inner and outer diameter ± 0.01 mm
Manufactured with bearing clearance amount taken into account of expansion and shrinkage of plastic caused by temperature change
Light rotation torque
Light weight
Light rotation torque by grease-less, lubricating oil free
Weight reduction for mechanical equipments
Rustless
Chemical resistant
It can be used in water-exposed environment, underwater, chemical solution.
(Weak against acids, but resistant to alkalis and organic solvents)
NonmagneticInner and outer ring cages are made of POM, balls are stainless steel (SUS304 or SUS316)
Electrical InsulationIt doesn't pass electricity, but attention is needed for static electricity
CleanroomGrease-less, lubricant free, good for clean environments
CautionWhen dust, abrasion powder, etc. enters inside the bearing, rotation torque may change. Some sealed types are available.
Custom-made
Options
・Change material - Select suitable material e.g. Conductive POM, PPS
・Change shape of outer ring e.g. R shape, U groove, V groove, recessed groove, flange shape
・Change inner ring material e.g. Stainless steel shaft screw, plastic shaft screw
・Specify dimension e.g. Change of outer diameter, inner diameter, widths, bearing internal clearance
・Production of plastic bearings assembled parts
e.g. Plastic roller, plastic collar, plastic washer, plastic holder
・Clean packaging e.g. Packaging after cleaning with pure water in clean room.

PLASTIC BEARINGS B-SERIES
※There is a clearance groove at the base of hexagon socket screw head and straight slot screw head.
