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.
Product Feature 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: The maximum price reduction is 63% compared with the standard product of MISUMI
Linear Bushings Feature 2: Holding high durability, low noise
■ Linear Bushings Test conditions
• Linear bearing (inner diameter 16) is matched with MISUMI guide shaft (PSFJ) to apply 63kg load and walk for 30km, and confirm the product damage and sliding noise.
■ Linear Bushings Test results
The economy series product ensures smooth sliding of steel ball, which have good durability and low noise
*Products circulating on the market are similar products randomly purchased by our company from online or offline markets
*The test data are obtained through testing by our company, which are for reference only

Linear Bushings If there are requirements for rust prevention, give priority to products with surface treatment of electroless nickel plating or those with low temperature hard chromium plating.Usage Method of Linear Bushings
| Product Drawings of Linear Bushings | Instructions for use Linear Bushings |
 | When the Linear Bushings, 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 Bushings, 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
■ 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.
③ Recommended grease filling interval: Usually every 6 months.
④ 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.
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.
