Roulements linéaires
The LM linear bearing is a compact cylindrical linear-motion component designed to operate with a compatible round shaft. Load-bearing steel balls roll along the shaft surface with relatively low frictional resistance, supporting smooth and responsive reciprocating movement.
The LM Series can be installed inside a suitable bearing housing, machine plate or linear-motion assembly. It is suitable for automation modules, CNC auxiliary mechanisms, packaging and printing equipment, 3D printers, laboratory devices and machine repair projects. Jinan Longqiao can assist buyers with model matching based on the shaft diameter, bearing dimensions, installation structure and operating requirements.
Présentation du produit
The LM Series is a standard cylindrical linear ball bearing used to guide machine components along a round or cylindrical shaft. Unlike a flanged linear bearing or a pre-assembled linear bearing block, the LM bearing has a compact sleeve-type structure without an external mounting flange or separate housing.
During linear movement, the load-bearing steel balls roll between the bearing assembly and shaft surface. This rolling point-contact structure helps reduce sliding resistance and allows the supported carriage, fixture or moving component to travel with smoother response than a conventional plain sliding bushing in compatible applications.
The cylindrical outer profile makes the bearing suitable for installation inside a machined bore, dedicated bearing housing or compatible support block. This gives machine builders flexibility when designing compact linear mechanisms or replacing an existing round-shaft bearing.
The supplied product information identifies low friction, stable operating characteristics, smooth movement and high motion sensitivity as the principal performance features. Actual positioning performance depends on the selected model, shaft quality, radial clearance, installation alignment, lubrication and operating load.
The LM Series is intended for CNC equipment manufacturers, automation integrators, industrial distributors, maintenance companies and factories requiring a practical round-shaft linear-motion component.

Caractéristiques du produit
Low-Friction LM Linear Bearing Motion
The internal steel balls roll along the cylindrical shaft rather than relying entirely on sliding contact. This helps reduce motion resistance and the driving force required to move a compatible carriage or machine component.
Smooth and Responsive Linear Travel
The rolling-contact structure supports sensitive response during starting, stopping and changes in travel speed. Correct installation, shaft alignment and lubrication are required to maintain smooth motion.
Compact Cylindrical Construction
The bearing uses a sleeve-type body without an integrated flange or external mounting block. This allows it to be installed in compact housings and machine structures designed around cylindrical bearing dimensions.
Compatible with Round-Shaft Systems
The LM Series is designed to work with a matching cylindrical linear shaft. It is suitable for machinery that already uses a round-shaft guidance system or requires a straightforward linear-motion arrangement.
Stable Motion Characteristics
The supplied product description indicates that operating resistance remains relatively stable as bearing speed changes. This supports consistent movement in compatible reciprocating applications, subject to the actual load and installation conditions.
Flexible Model Matching
Multiple shaft-diameter models are available within the LM product family. Buyers can select a bearing according to the shaft size, housing dimensions, load requirement and existing replacement model.
Suitable for New and Replacement Projects
The bearing can be considered for new automation mechanisms, distributor stock, equipment maintenance and replacement sourcing. Dimensional compatibility should always be verified before ordering.
Application du produit
The LM Series is designed for equipment requiring guided linear or reciprocating movement on cylindrical shafts. It is particularly suitable where a compact bearing must be installed inside a dedicated housing or machine structure.

Packing
Each LM linear bearing is identified, protected and packed according to its model and order quantity. Rust-prevention treatment may be applied to exposed metal surfaces according to the product specification and shipment conditions.
The bearing is placed in moisture-resistant wrapping or a protective sleeve to help prevent contamination and humidity exposure. The bearing bore and end components are protected from direct contact with hard objects.
Individual inner boxes, internal cushioning and reinforced outer cartons may be used to prevent collision and uncontrolled movement. Mixed models are labelled separately to reduce picking and assembly errors.
When bearings are shipped together with long linear shafts or other heavy components, pallet or wooden-case protection may be used according to the complete shipment configuration.
Storage
Store the bearings indoors in a dry, clean and ventilated environment. Keep them away from rain, condensation, corrosive gases and heavy dust.
Retain the original wrapping and rust-prevention protection before installation. Do not expose the bearing bore and internal components during long-term storage.
Avoid excessive stacking that may crush cartons or apply direct pressure to the cylindrical body and end components.
Handling
Support the outer cylindrical body when moving the bearing. Do not insert sharp tools into the bore or pull the product by the end components.
Avoid dropping, collision and contact with abrasive surfaces. Protect the outer diameter, bearing bore and end areas from dents, scratches, contamination and deformation.
Keep mixed models inside their labelled packages until they are required for installation.
Transportation
LM bearings can be prepared for international express, air freight, sea freight or rail transportation. Packaging is selected according to model size, order quantity, shipment route and whether matching shafts or other CNC components are included.
Before shipment, Jinan Longqiao checks the model, quantity, visible condition, product identification and packaging status.
Exact carton dimensions, gross weight and quantity per carton are provided after the final model and order configuration are confirmed.
