ZEN S6010-Z Kugellager (50x80x16)

This ZEN bearing measures 50x80x16 mm and weighs 0.261 kg; the specification table carries the supplementary technical details. This variant features stainless steel. The deep groove ball bearing is the most widely built rolling bearing type, and the reason is how little it asks: it carries radial load, supports moderate axial load in both directions, and demands little of the surrounding design.

The deep, closely conforming raceway grooves in the inner and outer ring capture the balls positively, so the bearing takes radial load and moderate axial load in both directions without a second bearing position to oppose it. Because the ball touches the raceway at a point, friction and heat stay low — the precondition for high speeds and for grease-for-life designs.

The limits follow from that same geometry: the small contact area caps load capacity against a roller bearing of equal size, and the bearing tolerates misalignment within narrow limits only, since angular error transfers straight into the raceway grooves. Seats in shaft and housing must therefore be aligned and geometrically accurate; where shaft deflection is expected, a self-aligning type belongs in that position.

The single shield runs without contact and holds back coarse contamination on its side; the open opposite side is left to the surrounding design, which seals it there or supplies the lubricant. The stainless steel version is intended for damp, wet or chemically loaded surroundings and for applications demanding freedom from rust; its load ratings sit somewhat below those of standard bearing steel.

The normal radial clearance recorded corresponds to the standard class and suits ordinary fits and temperature conditions.
