Configuration and Catalog Version
Rail/block group assignments below follow the regional pairing chart in the 2026 Chinese supplement. Body dimensions and load data remain identified by the original linked series drawing. Match the delivered catalog revision; a cross-version group letter is not a universal preload grade.
The E self-lubricator changes overall length C from 140.5 to 157.5 mm. Other dimensions follow the standard block drawing. The catalog weight is for the standard block; it is used only as a reference estimate for this E configuration and excludes an unlisted lubricator weight increment.

Features and Operation
A ball-separating chain controls ball spacing and reduces ball-to-ball contact noise and friction.
Lubricant pockets in the chain assist redistribution of lubricant. This does not remove the need to follow the catalog lubrication schedule for a standard block.
The caged-ball structure supports smoother motion; its load ratings and block lengths are specific to LSQH. Compatible guide rails are designated LSH in this catalog.
The E unit contains pre-lubricating felt, lubricating felt, a lubricant reservoir, partition, back cover and oil scraper. The felt contacts the rail ball grooves.
The catalog reports an additional friction force of approximately 5–7 N; the self-lubricator is not intended for applications requiring exceptionally low resistance.
The LSQH20 durability example used 30 m/min, a 1200 mm stroke and ISO VG680 extreme-pressure lubricant. After 1000 km, about 20% of the grease was consumed. The stated possible life above 4000 km is a test-based expectation, not a guaranteed life for this model or every operating condition.

Dimensions are in millimetres unless another unit is shown. Letter labels follow the catalog drawing; assembly height is not the height of the loose block.

Compatible Parts and Assembly
Use with LSH35 rail of compatible accuracy and the specified rail/block pairing group. This listing is an individual block and does not include a rail.
This model specifies A01: straight oil-line adapter, fitted at the M6X0.75 block lubrication port with PT1/8 line-side connection.
The corresponding replacement accessory is L-P-A01; check clearance above the block and the oil-line layout before installation.
Installation, Lubrication and Use
Standard-block lubrication reference: factory grease Kluberplex GL261; use the same product or an equivalent grade. Initial amount 10 cm³; replenishment 3.8 cm³.
For the E self-lubricator, inspect lubrication under the actual mounting orientation and duty. The standard-block replenishment figures above are a reference; the self-lubricator has its own reservoir and test conditions.
Wipe off storage anti-rust oil before applying the working lubricant. Do not mix incompatible greases or oils.
Install on a clean, accurate reference surface. Keep block datum marks aligned; tighten the rail while holding its datum edge against the machine reference.
Use the supplied plastic transport rail when transferring an individual block. Align it straight and support the dust seals; avoid angled insertion or rapid removal.
Avoid impact, dropping and contamination. Store horizontally, sealed and rust-protected, away from humidity and high temperatures.
The standard-series operating environment should not exceed 80°C; the catalog separately states a maximum temperature of 100°C. This is not a continuous 100°C operating rating.
Rail mounting screw M8: catalog tightening torque is 3040 N·cm into iron, 2010 N·cm into casting, or 1470 N·cm into aluminium alloy. Choose the value for the mounting material; these are not interchangeable block-bolt torques.
For oil lubrication, the catalog recommends approximately 30–150 cSt viscosity. Adapter height may extend above the block; provide clearance. Non-horizontal or inverted mounting can change lubricant distribution.
Series Ordering Options
These are catalog options for this product family. Only the codes in the ordered model define the supplied configuration.
Match the rail series and size, block form and length, accuracy and rail/block group before ordering. A group letter is a manufacturing pairing code, not a standalone preload rating.
Grease nipples and straight/elbow oil-line adapters are selected by the final accessory code. Self-lubricating E blocks have a longer C dimension; standard, DD and ZZ end arrangements must not be assumed to share one overall length.
