Precision rolling bearings since 2004

The right bearing, specified correctly, delivered on time

Over 12,000 catalogued designations across ball, roller, thrust and housed units — each one with full dimensional and load data, interchange references and engineering support from people who read drawings for a living.

  • 20+ years in rolling bearings
  • 12,000 designations catalogued
  • 48 h quotation turnaround
  • ISO 9001 certified manufacturing

Why specify SXX

A bearing is a calculation before it is a component

Most premature failures are specification failures — the wrong clearance for the fit, the wrong seal for the environment, a limiting speed read from the wrong column. We publish the complete data set for every designation and we will work through the duty with you before you order, not after the bearing comes back.

  • Measured, not claimed

    Every production lot is checked for raceway geometry, radial clearance, hardness and vibration level. Certificates of conformity ship with the goods and stay available on your part pages.

  • ISO 9001 discipline

    Material traceability from 100Cr6 billet to finished designation, with heat-treatment records held for ten years. Audited annually, and we will host your audit too.

  • Engineering on the phone

    Application engineers answer enquiries directly — life calculations, fit and clearance selection, lubrication intervals and failure analysis, not a ticket queue.

  • Stock that reflects reality

    Ex-stock lines are genuinely on the shelf in Jinan and Rotterdam. Made-to-order lines carry an honest lead time, quoted before you commit.

Same boundary dimensions. Seal and clearance are listed beside the match, not assumed.

Cross-reference

Replacing another brand? Start from their designation

Our interchange index maps common designations to the SXX equivalent and, crucially, tells you where the equivalence stops — clearance class, cage material and seal profile are listed side by side so you can see what actually changes on your machine.

  • Dimensional equivalence shown against the ISO boundary dimensions
  • Differences in clearance, cage and sealing called out explicitly
  • Reviewed by an engineer before it reaches the page

Customers

Specified once, ordered again

Maintenance teams and buyers, on the part that arrived and the data that came with it.

  • We sent a failed 22216 and a sketch of the housing. The reply named the clearance, the cage, and a seal that would survive the wash-down. It has now run two seasons.

    Helena Voss Maintenance lead, harbour cranes
  • The interchange note was the useful part. It did not just say “equivalent”. It showed where the seal and the clearance class differ from the bearing we were taking off.

    Marcus Adeyemi Reliability engineer, cement mill
  • Quotation in a day, and the dimensions on the page matched the bearing in the box. That is rarer than it should be.

    Priya Raman Purchasing, gearbox OEM
  • We stopped guessing the limiting speed. The page had the grease and the oil figures in separate columns, and the engineer confirmed which one applied to our fan.

    Jonas Keller Plant engineer, paper mill
  • Three designations, one shipment, certificates in the same envelope as the packing list. Our stores team did not have to chase anyone.

    Amira Hassan Stores supervisor, sugar refinery
  • The housed unit arrived with the insert we had asked for, not a close relative. Fit on the shaft was as drawn.

    Luis Ortega Workshop manager, agricultural OEM
  • When a conveyor bearing failed on a Friday, they had the spherical on the shelf and told us the lead time before we committed. Both were accurate.

    Chen Wei Reliability, bulk terminal
