Definition of dynamic load ratings
Rigidity
Combining a radial Linear Bushing with a continuously supported guide shaft ensures a precise, rigid design.
- The following figure shows load-dependent spring. The diagram applies for installation:
- Without preload
- With zero clearance (no preload)
- for load direction ρ = 0° – 90° and 270° – 360°
Radial Linear Bushing rigidity
Installing with preload reduces spring. Additional spring in all parts of a linear guide (housing, shaft, shaft support rail) depends on the load direction. Guideline values for total spring with R1076 and R1010 elements: load direction factor multiplied by spring ∂ (from right diagram).
| 1) | F = load N |
| 2) | ∂ = spring mm |
Overall deflection depending on the load direction
| Load direction ∂ | 0° | 90° | 180° | 270° |
| Overall deflection | 1 • ∂ | 1,8 • ∂ | 3,5 • ∂ | 1,8 • ∂ |
Effect of load direction on load rating
The load ratings C and C0 specified for Radial Linear Bushings apply for load direction ρ = 0°. If the external load is at an angle ρ = 90° – 270°, a reduced load capacity must be factored in. The dynamic load rating is then determined by multiplying the specified dynamic load rating C or C0 by the load direction factors fρ or fρ0. This reduced load capacity can be avoided by careful installation of the radial Linear Bushings.
