KH is the mini press-fit linear-bearing family member of the catalogue linear-bearing range. The KH mini pressing bush is a compact linear-bearing series with optional single P or double PP sealing. 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 65. The documented selection range is shaft diameter 6–50 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.
Key Features
Technical Specifications
| Item | Documented Value | Why It Matters |
|---|---|---|
| Series | KH | Catalogue family identifier |
| Design form | Mini press-fit linear-bearing family | Mounting / envelope decision |
| Documented range | shaft diameter 6–50 mm | Use the exact model row for final dimensions |
| Key specification fields | model / shaft d / outside D / length B / dynamic C / static Co / weight | Check drawing symbols and tolerance columns |

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.
Applications
KH bearings fit small automation, compact instruments and mechanisms where a full-size cylindrical linear bearing consumes too much radial space.
The P and PP seal choices help match contamination protection to the duty without changing the basic miniature concept.
Selection Guide
Select by shaft diameter and required body length, then decide whether the application needs no seal, one seal or two.
The catalogue naming example KH 20 30 PP shows that shaft size, length and seal arrangement all belong in the order code.
Installation & Maintenance
Use a controlled press fit and support the thin outer shell uniformly during installation.
Keep miniature shafts clean; small particles represent a larger proportion of the running clearance and can quickly turn smooth travel into rough motion.
