Can UU Seals and Felt Seals be Installed Together on Linear Bearings for Dust Prevention?
Yes, it is possible.
The linear bearings already come equipped with UU seals. For the felt seals, a supporting seat is necessary.
Installation involves securing them with a retaining ring:
Note: Felt seals can be installed on LM types (from LM6 to LM100). For other models, only UU seals can be used.
Can Surface Treatment be Applied to Linear Bearings?
Partial models may undergo surface treatment, but certain models might not be suitable.
How Should Linear Bearings be Installed?
When installing linear bearings, avoid fixing the bearing sleeve by compressing the outer surface with a fixing bolt, as this can cause deformation of the bearing sleeve. Instead, use retaining rings or retaining plates.
How Much High Temperature Can the Sealing Felt Ring Inside the Linear Bearing Withstand?
It can withstand temperatures up to 120 degrees Celsius.
What Lubricant is Generally Used?
Use AFB-LF lubricating grease. We also recommend high-quality lithium soap-based grease No. 2. Turbine oil, engine oil, and spindle oil are commonly used lubricants.
Can Linear Bearings be Used in Rotary Motion?
Linear bearings cannot be used in rotary motion. Attempting to do so may result in accidents.
What Material is Used for the Optical Axis?
Generally, materials such as SUJ2, SK3-6, S55C, etc., are used for the optical axis. The optical axis undergoes surface hardening through high-frequency induction hardening.
Is the Surface Hardness the Same for Every Optical Axis?
The hardness is the same, but the depth of the surface hardness layer varies with different optical axis diameters.
