Product Overview of Linear Bushings
The embedded flanged linear bearing does not extend to the opposite side of the mounting surface, so there is sufficient space on the opposite side of the mounting surface.
Product Features of Linear Bushings
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.
Dimensional Drawing of Linear Bushings
When this product of Linear Bushings is initially delivered, its color may be partially inconsistent with the photo, in which case the actual product shall prevail, without prior notice.Specifications Overview of Linear Bushings
| Housing | Ball | Retainer | Operating Environment Temperature |  Accessories | ||
 Material |  Hardness |  Surface Treatment | Material | Material | ||
| Equivalent to SUJ2 | 58HRC～ | No Surface Treatment Electroless Nickel Plating | Equivalent to SUJ2 | Resin | -20 to 80℃ | Seal packing Material Nitrile Rubber (-20 to 120℃) |
If there are requirements for rust prevention, give priority to products with surface treatment of electroless nickel plating.Usage Method of Linear Bushings
| Product Drawings of Linear Bushings | Instructions for use | ||||||||
 | When 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. | ||||||||
 | Linear 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. | ||||||||
 | Linear bearing is not suitable for repeated plugging and unplugging. | ||||||||
 | When 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
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 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.
