Stacking bearing races without precise tolerances and matched sorts does not provide ultimate bearing system capacity. Optimized ball raceway geometry with matched and numbered races assures load share right through the stack and right out of our industry leading stack packaging.

• Properly sized Rockbit balls for ultimate stress transfer through stack
• Optimized ball raceway geometry for load capacity and wear ability
• Tolerance matching and sorted races for immediate load share
• Multiple runs on races due to lower wear ability with 62Hrc raceway hardness
• Serialized and numbered races for traceability and serviceability
• Safe and weatherproof packaging
• North American materials and production with low lead times
