ST standard stroke-bearing family linear bearing for maximum stroke 20–132 mm. Built for round-shaft linear motion, with model-specific dimensions and load ratings selected from the supplied catalogue.
MOQ: 50 pcs. Minimum order value USD 1,500; mixed orders and trial quantities welcome.
ST is the standard stroke-bearing family member of the catalogue linear-bearing range. ST stroke bearings combine rotation with a limited linear stroke by using balls between the outer cylinder and shaft. The practical buying question is whether its envelope and mounting style match the shaft, housing and carriage already designed into the machine.
The supplied catalogue places this series on pages 63–64. The documented selection range is maximum stroke 20–132 mm. Rather than treating the series code as interchangeable with a similar-looking bushing, confirm the exact diameter family and the mounting geometry before an RFQ is released.

Catalogue note: The source provides model-by-model tables. This import row intentionally keeps the published family limits and field structure; final dimensions, C/Co ratings and mass must be taken from the selected catalogue model rather than inferred from a neighbouring size.
ST bearings are used when a component must both rotate and move axially through a defined stroke, rather than travel continuously along a long guide shaft.
They fit special-purpose mechanisms, adjustment devices and machine elements where compact combined motion is more important than unlimited linear travel.
Choose the bore and required axial stroke together. A bearing with the right shaft diameter but insufficient stroke is not an acceptable substitute.
Check the exact model table for ball-row count, load rating and envelope dimensions; the maximum stroke varies substantially across sizes.
Keep the working shaft smooth across the entire stroke and avoid hard stops that impact the bearing at travel limits.
Inspect for contamination and track marks at reversal points, where repeated motion can concentrate wear.
