Product Description

What this part is

H38KDD12 sealed ball bearing with a U-groove outer ring. The outer race carries a concave U-shaped track rather than a flat or crowned one, so the bearing seats and self-centres on round rail, rod, cable or wire. Rolling Elements: Ball. Number Of Rows: 1. Design Units: Inch. GTIN: 637400580858.

What these specs mean in practice

Closure Type: Contact seals both sides. The seals hold the factory grease charge in and keep swarf and washdown out of the raceway, so the bearing is greased for life.

The U-groove profile carries load on two flanks rather than a single line, which is what holds a round rail or wire centred in the roller.

Quantity and configuration

Unit Quantity: 1 Pc.

Interchange guidance

Interchange on a U-groove roller is set by the groove profile and the mounting envelope together, so a match is made against the H38KDD12 groove form itself.
