STD SKATES 628 ZZ SKATE RATED "STANDARD" BEARINGS

STD SKATES 628 ZZ SKATE RATED "STANDARD" BEARINGS

16 pieces

Bearings with two steel seals and cage, balls, outer ring, and inner steel ring.

For 8 mm axle diameter.

Skate Rated STANDARD, special bearings for figure skating.

The "Skates Rated" calibration is based on a specific mechanical adjustment designed to withstand the forces involved in skating.

1. Radial Clearance:

This takes into account the space between the balls and the raceways of the rings. In the Skate Rate calibration, an intentional clearance is left. This prevents the bearing from seizing up when a little dirt gets inside or when heat expands the metals during intense training.

2. Lateral Load Capacity:

The bearing raceways have deeper grooves to prevent the balls from slipping off their axles or "biting" the metal when subjected to lateral pressure.

3. Groove Depth

Calibration: A bearing calibrated for skating has deeper ball grooves to increase structural stability under impacts (jumps, spins).

Summary

1. Beginner: Balanced calibration between speed and impact resistance, STANDARD

2. Precision: Calibration with finer tolerances for maximum inertia (rolls longer without pushing off). DEEP GROOVE

3. Competition: Calibration focused on minimal friction, with mirror-polished balls and ceramic coating. CERAMIC
