Specification Brand : AUZHU BulletPoint1 : SCK is the model number for this product. The dimensions you choose are: shaft collar with a bore diameter D of 22 mm; outer diameter E of 42 mm; width B of 15 mm. Different capital letters are used in the product drawings to represent the dimensions of the various detail positions on the product. The specific dimensional data can be found under the corresponding letters in the specification sheet, and several sizes are available. BulletPoint2 : [Material of the shaft collar: 304 stainless steel]; [Surface treatment of the shaft collar: stainless steel brushed (#4 Satin)]; [Material of the fastening screw: stainless steel]; [Surface treatment of the fastening screw: stainless steel brushed (#3 Satin) ] BulletPoint3 : Each shaft collar is equipped with a fastening screw. The inner slot of the screw is hexagonal and it is recommended to use an Allen wrench to turn the screw. The advantage of this shaft collar is that the locking effect can be adjusted by turning the screw, so this shaft collar can also have good locking ability when locking a shaft with tolerances or when the surface of the shaft is not flat. BulletPoint4 : Feature · Post assembly installation and removal are possible, making for easy maintenance. Shaft damage from tightening can be avoided. Rings, set collars and shaft collars can be used in multiple ways in machine and fixture fabrication. They secure shafts and axles, act as a positive stop or as an attachment option for additional function elements. BulletPoint5 : Warm reminder: the data on this page are in metric millimetres. As the sizes are measured manually, there may be a slight error, but the error will be less than ±0.5 mm, please understand.
