LM / LM-OP Open-Type Graphite-Plugged Linear Bushings
Open-type LM-OP graphite-plugged copper-alloy linear bushings for supported shafts; the supplied photo also shows the closed LM version for comparison.
Information Required for a Quotation
State whether you need an open LM-OP or closed LM version, shaft diameter, outside diameter, length, shaft support arrangement, load and quantity.
Standard sizes and custom production are reviewed against availability and your drawing before quotation.
Construction and Selection
The LM-OP option is an open-type graphite-plugged copper-alloy sleeve for a supported shaft. The supplied image also shows a closed LM-type sleeve; the open section and its orientation must match the shaft support and housing.
Specifications to Confirm

Engineering Review
An open-type sleeve should be reviewed for stiffness, support clearance and direction of load before substitution for a closed sleeve.
