ST…B heavy-duty stroke-bearing family linear bearing for maximum stroke 8–88 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...B is the heavy-duty stroke-bearing family member of the catalogue linear-bearing range. ST...B is the heavier-duty stroke-bearing series, retaining combined rotational and axial movement in a more robust catalogue family. 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 8–88 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.
| Item | Documented Value | Why It Matters |
|---|---|---|
| Series | ST...B | Catalogue family identifier |
| Design form | Heavy-duty stroke-bearing family | Mounting / envelope decision |
| Documented range | maximum stroke 8–88 mm | Use the exact model row for final dimensions |
| Key specification fields | model / maximum stroke / ball rows / dr tolerance / D tolerance / L / l / T / t / d / r / C / Co / weight | Check drawing symbols and tolerance columns |
| Source | Catalogue pp. 63–64 | Supplied bearing catalogue / outline |
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...B suits combined-motion mechanisms where the standard stroke series does not provide the desired duty margin or envelope.
Its shorter documented maximum-stroke range compared with ST makes the required travel a decisive selection input.
Confirm the stroke first, then compare load rating and dimensions against the standard ST family. Heavy-duty does not mean that any ST...B size will meet a longer travel requirement.
Use the exact model row for C, Co, shaft diameter and body dimensions; the B suffix changes the family rather than serving as a generic strength label.
Avoid using the bearing itself as the mechanical end stop and protect the working surface from impacts.
Maintenance should focus on smooth reversal, contamination control and any increase in play under the actual combined-motion cycle.
