How to carry out regular maintenance for the product?

MISUMI recommends that linear bearing is regularly replenished with grease, and it is recommended to do so once every six months. When the moving distance is long, it is recommended to move once every three months or when the moving distance exceeds 1000km within the time limit, the 1000km shall prevail.

Comparison of antirust ability of linear bearings?

Antirust ability from strong to weak: Low Temp. Black Chrome Plating → No-Electro Nickel Plated → No Surface Treatment. Standard grade bearing steel is easy to rust, so it is necessary to apply anti-rust oil regularly.

Product Overview of Linear Bushings

Linear Bushings come with the function of performing linear and rotational composite movements, which can achieve significant miniaturization compared to the traditional method of combining linear bearings and rotating bearings.

Product Features of Linear Bushings

Linear Bushings are used to provide linear motion and rotary motion. Due to the point contact between the ball and the rolling surface, low friction rolling motion can be performed.

Feature 1: Effective utilization of space. The combination of the guide shaft and the Linear Bushings enables effective use of space, suitable for small mechanism designs.
Feature 2: Good interchangeability. Linear bushings have good interchangeability because they can be used with shafts randomly.
Feature 3: Appropriate specifications can be selected according to the conditions of use.
Feature 4: More cost effective than the Linear Bushings.

Unlike Linear Bushings, a non-circulating ball mechanism is used, so the stroke is limited. Please be sure to use it within the maximum stroke.

Precautions

■ Regular maintenance:
① Before use, please apply grease to the ball row inside the linear bushing, and then replenish it in due course. Grease forms an oil film on the surfaces of steel ball and rolling surface (guide shaft·bushing) of linear bushing, which effectively reduces friction and prevents sintering. Grease reduction and aging will greatly affect the life of linear bushing.
② Recommended grease: lithium soap grease. Click

Grease
for details. ③ Recommended grease filling interval: Usually every 6 months.
④When the moving distance is long, it is recommended to move once every three months or when the moving distance exceeds 1000km within the time limit, the 1000km shall prevail.
⑤ When the linear bushing is subjected to large moment load (eccentric load), one piece of single type is not applicable, so it is recommended to use one piece of double type or multiple pieces of single type.

■ Dust prevention measures:
If dust or foreign matter enters the inside of the linear bushing, it may damage the circulation of steel balls, resulting in unexpected failures. When used in harsh environment, please install dust cover and protection cover, etc.

■ MISUMI linear bushing is recommended to be installed on the holder with H7 tolerance. The linear bushing is in clearance fit with the housing.

■Unlike linear bushings, a non-circulating ball mechanism is used, so the stroke is limited. Please be sure to use it within the maximum stroke.

■For preloaded use, it is recommended to use a MISUMI quenched guide shaft with an outer diameter tolerance of h5.

■ MISUMI linear bushing is recommended to be combined with guide shaft with quenching g6 tolerance.
