Tritan 6307/C3 Radial Ball Bearing 35 mm collectible

Radial ball bearing for industrial use

The Tritan 6307/C3 is a metric radial ball bearing built to the 6307 industry number with a 35 mm bore and 80 mm outside diameter. It is made from alloy steel rings and AISI 52100 grade alloy steel balls held in a steel cage. The open closure suits oily or greasy environments where sealed units would trap contaminants.

Open closure limits protection in dirty settings

Without shields or seals the bearing relies on the surrounding lubrication to keep debris out, so it is not suited to dusty or wet locations where ingress would accelerate wear. The ABEC 1 rating and +0/-0.012 mm bore tolerance give standard precision rather than the tighter fits needed for high-speed spindles. Dynamic radial load capacity reaches 7,500 lbf within those limits.

Transparent finish shows internal condition

The clear colour lets maintenance staff verify lubrication level and ball condition without disassembly. A 21 mm outer ring width fits standard housings for the 6307 series and the design omits a retaining ring, so axial location must be provided by the shaft shoulder or housing. Alloy steel construction resists fatigue in continuous power-transmission duty.
