❓ Frequently Asked Questions — 206KRRB6 Hex Bore Bearings
✅ What is the advantage of hex bore vs. round bore?
Hex bore provides positive torque transmission without keyways or set screws, eliminating slippage under high vibration — critical for cultivators, balers, and mowers.
✅ What is the difference between 206KRR6 and 206KRRB6?
206KRR6 uses standard seals. 206KRRB6 features enhanced triple-lip seals for extreme dust/moisture conditions. Both share same dimensions and load ratings.
✅ What is the lead time for 206KRRB6?
Stock: 5–7 working days. Custom branding/packaging: 15–20 days after sample approval.
✅ Do you offer free samples for testing?
Sample available within 5 days. Sample cost is refundable for bulk orders ≥ 500 units.
