Product Overview of Linear Bushings

The flanged Linear Bushings, linear bearing integrates the linear bearing with the support, which is compact in structure and easy to assemble to the mechanism accurately and simply.
The middle flanged linear bearing allows workpieces to be installed near the center of the linear bearing body, ensuring good balance on two sides of the flange, as well as decentralized load space.

Product Features of Linear Bushings

Linear Bushings, Linear bearing is a linear type motion guiding mechanism matched with linear guide shaft. The steel ball rolls circularly along the track groove formed by the shell and the retainer, and the linear bearing reciprocates linearly relative to the guide shaft.
Through the rolling of steel ball, high-efficiency movement with low friction resistance can be realized.

Linear Bushings Feature 1: Effective utilization of space. The combination of the guide shaft and the linear bearing enables effective use of space, suitable for small mechanism designs.
Linear Bushings Feature 2: Selection can be made based on operating environment. The outer cylinder of the linear bearing is made of steel or stainless steel, and the retainer is made of stainless steel for harsh conditions or resin for low noise.
Linear Bushings Feature 3: Good interchangeability. Linear bearings have good interchangeability because they can be used with shafts randomly.
Linear Bushings Feature 4: Appropriate specifications can be selected according to the conditions of use.
Linear Bushings Feature 5: More cost effective than the linear guide.

Usage Method of Linear Bushings

Product Drawings of Linear BushingsInstructions for use Linear Bushings
Usage method of the middle flanged linear bushingWhen the linear bearing is under heavy load (unbalanced load), one piece of single liner type is not applicable. It is recommended to use one piece of double liner type or multiple pieces of single liner type.
The middle flanged linear bushing has low price and short delivery timeLinear bearing is not suitable for rotating motion in structure. If you rotate forcibly, it may cause damage to the product. Please pay attention during use.
The middle flanged linear bearing has large inventory and assured qualityLinear bearing is not suitable for repeated plugging and unplugging.
The middle flanged linear bushing is cost effective and has abundant stockWhen inserting the guide shaft into the linear bearing, please align the center and insert it slowly, otherwise the steel ball will fall off or the retainer will be deformed.

Precautions of Linear Bushings

■ Linear Bushings Regular maintenance:
① Before use, please apply grease to the ball row inside the linear bearing, 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 bearing, which effectively reduces friction and prevents sintering. Grease reduction and aging will greatly affect the life of linear bearing.
② Recommended grease: lithium soap 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 Bushings, linear bearing is subjected to large moment load (eccentric load), one piece of single liner type is not applicable, so it is recommended to use one piece of double liner type or multiple pieces of single liner type.

■ Linear Bushings Dust prevention measures:
If dust or foreign matter enters the inside of the linear bearing, 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 bearing is recommended to be combined with guide shaft with quenching g6 tolerance.

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

Frequently asked question (FAQ)

Question: How is linear bearing maintained regularly?
Answer: 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.
Question: Comparison of antirust ability of linear bearings?
Answer: 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.
