Chrom Carbon Steel Ceramic Skateboad Bearings 608 Bearing ABEC 7 9 for Skateboard Scooter 8x22x7mm

 ball bearing 608

Brief introduction

Deep groove ball bearings are the most representative and widely used bearing. It can withstand axial loads in both directions, in addition to radial loads, even at high speed. They are available for low noise and low vibration. Bearings with mental shields and rubber seals are pre-lubrecated by some grease. Deep groove ball bearings with filling slots have the same dimensions with the standard ones. Filling slot bearings have a higher radial load carrying capacity than bearings without filling slots.

Generally in the skateboard industry, 608zz (8x22x7mm) is the most popular and most widely used bearing. A vast majority of customers will choose this specification, while some may use other sizes as well,include 6900zz(10x22x6mm), 627zz(7x22x7mm), 688zz(8x16x5mm).

Working Principle

Deep groove ball bearings mainly take radial load as well as both radial&axial load. When with only radial load, the contact angle is zero. With radial clearance, they can withstand large axial load. The friction coefficient is small and the speed is also high.

Types

1.Single-row deep groove ball bearing
2.Single-row deep groove ball bearing with dust cover
3.Single row-deep groove ball bearing with dust cover and seal ring
4.Single-row deep groove ball bearings with the outer ring on the stopper groove  and   snap ring
5.Deep groove ball bearing with filling slot
6.Double-row deep groove ball bearing

Advantages of 608 deep groove ball bearing

• Excellent for high speeds
• Good radial load capacity
• Acceptable axial load capacity in both directions
• Have low torque capacity at startup and running speeds
• Can operate with low noise
• Require little maintenance

As flexible as the performance is, the configurations of single row ball bearing is also as versatile. These bearings often have 

steel shields or rubber seals installed on one or both sides and are prelubricated with grease. Also, 

snap rings are sometimes used on the outside edge. While many different retainers are available, 

pressed steel cages are most commonly used. Even tapered bores are available upon special order.
