Why should we prevent the dust into the linear bearing block?

The performance and stability of the linear bearing block (Linear Bearings, linear bearing blocks, linear guide blocks, guide rail carriage, linear guide sliders, bearing truck) directly affect lifespan of the whole linear block. If the bearing block is in a dust environment, the intrusion of dust, dirt, and other impurities can impact the lifespan of the linear bearing block. If dust dirt, and other impurities enter the back of the linear bearing blcok, it will cause abnormal wear and shorten the service life. So in this article, how to enhancing the dust-proof performance of the guide slider, introduce the accessories of dust-proof sliders, how to minimize dust entry the linear bearing block.

Linear bearing block structure:

Dust proof accessories prevent material debris and dust particles from entering the block and causing damage to grooved surfaces.

Normally dust-proof accessories include grease fitting, washes, scraper, end seal,

spacer plate, plug screw. End seals not only can prevent the ingress of substances outside such as dust particles, chips or liquid into the block’s ball tracks, but also reduce the amount of lubricant lost. 

Linear bearing block working condition:

1. Temperature Range: Standard working temperature is between -20°C to 80°C. 

2. Humidity and Corrosion

Humidity Control: Avoid prolonged exposure  in a high humidity, it will induce the rust.

Corrosion Protection: In corrosive environments (e.g., chemical or marine settings), please use stainless steel or chrome plated linear bearing blcok.

3. Cleanliness: The working environment should be kept clean to prevent dust, also please use the sealing accessories.

4. Lubrication Conditions

Regular Lubrication: Ensure the linear bearing block is adequately lubricated during operation to reduce friction and wear.

5. Maintenance and Care

Regular Inspection: Periodically check the linear bearing block for wear and replace worn parts in time.

Cleaning and Maintenance: Regularly clean the guide rails and linear bearing block to maintain surface and lubrication.
