27606 Steep Angle Tapered Roller Bearing (30x72x28.75mm)
- Dimensions: 30mm (Bore) x 72mm (OD) x 28.75mm (Width)
- Precision Class: Available in Class 6 (6-27606) for lower vibration.
- Steep-angle cup design heavily outperforms standard 32306 under unidirectional thrust.
- High-purity alloy steel prevents premature subsurface rolling fatigue.
6-27606, 32306B, 32306 (High Contact Angle Variant), GOST 27606，
The 27606 bearing (frequently designated as 6-27606 or modernized as 32306B) is a specialized steep-angle tapered roller bearing measuring 30x72x28.75mm. Engineered to replace standard profiles where severe backward pushing forces occur, its high contact angle transforms axial stress into manageable radial housing loads. This exact dimensional fitment ensures absolute gear mesh stability and eliminates microscopic shaft displacement under heavy torque.
