Super Open Linear Bearing SLM-OP

Super Open Linear Bearing SLM-OP
ISUTAMI SLM-OP super open linear bearings, also known as SLM-OP super open linear ball bearing or SLM-OP super open linear bushing bearings. S is the abbreviation of Super, LM is the code name of the Asian standard series in linear bearings, and OP is the abbreviation of Open. This model is suitable for Asian markets using metric units in Japan, Korea, Singapore, etc.

SLM-OP super open linear bearing body is composed of a POM holder, some high carbon bearing steel balls and high carbon steel ball plates. The sealing ring is from one or two sides of the bushing, usually marked with P or U in the model number.

Super Open Linear Bearing SLM-OP Features

SLM-OP super open type linear bearing:
The number of ball columns is in the range of 4-5 columns;
The inner diameter (dr) ranges from 16 to 50 mm;
The outer diameter (D) ranges from 28 to 80 mm;
The length (L) range is 37-100mm;
The opening angle (α) ranges from 50° to 80°;
The basic dynamic load rating (C) is 153-1169kgf, which is 2-3 times that of the LM-OP open type linear bearing of the same specification;
The basic static load rating(Co) range is 128-810kgf, which is basically larger than the LM-OP open type linear bearing of the same specification.

SLM-OP super open linear bearing can be replaced by LM-OP open linear bearing, generally mounted to SMA standard linear bearing pillow blocks, SMA-S short linear bearing pillow blocks, SMA-L long linear bearing pillow blocks, with the corresponding linear shaft and rail.

The basic dynamic load rating of the SLM-OP super open linear bearing is greater than the basic static load rating, this is different from the ordinary LM linear bearing, and the difference between the two loads varies significantly with the change of the size. About weight, since the main frame uses POM engineering plastics, the weight is smaller than that of ordinary LM-OP linear bearings of the same specification. Moreover, its moving life is 27 times that of ordinary LM-OP linear bearings of the same specification.
In addition, the ball plates of SLM-OP super open type linear bearing is convex, which can provide the pivot point in the center. The pivot point can automatically adjust the bearing by 1°. This performance can compensate the inaccurate machining of the base point and reduce the installation time and installation costs.

SLM-OP super open linear bearings can be used in high performance automation equipment, industrial robots, electrical equipment, measuring instruments, etc.
