BK20 BALLSCREW SUPPORT (suits 25mm Machined Ballscrew)


  • Model: BK20
  • Shipping Weight: 1.5kgs
  • 3 Units in Stock

You are looking at one piece of BK20 driven end ballscrew support.  The advantage of the BK20 is that it accommodates bottom mounting, and face mounting.

This ball screw support is the perfect MATCH for our 25mm machined ball screws (see other listings).

This is a superior quality Taiwanese made unit fitted with Japanese bearings.  Don't waste your money on cheaper Chinese model's in the market, they are unrated, and quality varies from unit to unit.  From personal experience, there is a massive difference between our units, and the cheaper ones.

The BK20 fits the driven end of the ball screw and includes 2 MATCHED angular contact bearings (with C7 rating) to support the ball screw while resisting thrust loads imposed onto the screw.  The two bearings are clamped into the housing with 4 screws ensuring there is no lateral movement of the ball screw giving the greatest accuracy possible!

Included with the BK20 are 2 x 20mm spacers and a M20 x 1mm square nut.  There are even 2 grub screws installed in the nut ensuring that the nut will not loosen during use!

  • 20mm bore BK20
