Lee Shafting

60 Plus Shafting -Made from high carbon C1060 steel provides high machinability. The shafts are manufactured with the best care to ensure maintained straightness, roundness,and surface finish. Ranging from 1/4" - 3" in diameter and lengths up to 148".

Ready Shafts - Offering immediate delivery, available in C1060 and 440C linear shafting. Ranging from 1/4" - 1-1/2" in diameter, and maximum length up to 72".

440C Shafting - Corrosion resistant shafting. Ranging from 1/4" to 2" and a maximum length of 170".

Pre-Drilled Shafting - Offered in both 60 Plus and 440C shafting, pre-drilled with a standard industrial hole pattern meeting most application requirements. Holes are drilled and tapped to the center of the shaft. Ranging from 1/2" - 3" and up to 193" in length.

Custom Shafting - Using 60 Plus or 440C shafting as the base material, experienced machinists have the capabilities to do the following: threading, diameter reduction, coaxial holes in end of shaft, radial holes to center of shaft, radial holes drilled and/or tapped through shaft, joined shafts to achieve longer lengths, retaining ring groove, keyways, flats, gun/deep hole drilling.

Support Rails & Guides

Shaft Support Rails "SR"- Composed of 6061-T6 extruded aluminum providing great support for precision shafting. Reducing warping, twisting, and the need for counter bored holes in the base. Available in 24" and 48" lengths, and diameters of 1/2" to 3". "SRI 1" and "SRI 2" are for light load applications, along with "SR-PD" for a pre-drilled option.

Low Shaft Support Rails "LSR" - Designed as a 40% lower profile for compact linear motion systems. Composed of AISI C1018 steel and available in lengths up to 48" and diameters 1/2" to 3". "LSRI 1" and "LSRI 2" are available as intermittent supports, along with a pre-drilled option "LSR-PD".

Low Support Guides "LSG" - Consisting of 60 Plus or 440C shaft with with a low support rail providing a low profile. Designed to support plain bearings and some linear ball bearings. When the shaft is appearing to be worn, rotate it 180° to provide a "fresh surface" for the bearing. Sold as a two-piece set, rail and shaft and can be bolted down to a mounting surface. Diameters available between 5/8" to 2".

Support Blocks


Support Blocks "SB" - Provide support without requiring machining to the shaft. Supports are manufactured from C1045 steel and range from 1/2" to 3" shaft sizes.

Bearings & Pillow Blocks

Precision Plus Linear Ball Bearings - Long running life and high accuracy. Available as a plain bearing or mounted in an aluminum housing with either opened or closed configurations. Maximum Load Capacity: 105–1930 lb for Closed Bearings, 265–1930 lb for Open Bearings Shaft Diameter: 3/8" to 1-1/2" for Closed Bearings, 1/2" to 1-1/2" for Open Bearings.Lee Linear

Precision Plus Linear Ball Bearing Pillow Blocks - All of the same benefits of the Precision Plus Linear Ball Bearings with the additional advantage of mounting. Available in an opened or closed style. Load Rating: 255–2000 lb for Closed Bearings, 230–1560 lb for Open Bearings. Shaft Diameter: 1/2–1-1/2 inches for Closed and Open Bearings

Precision Linear Ball Bearings - Superior to standard linear ball bearings due to their accuracy, travel life, and high load handling. Available as an opened or closed style and the optional seals. Bearing Mass: 0.020–2.75 lbs for Closed Bearings, 0.080–2.75 lbs for Open Bearings. Dynamic Load Capacity: 19–1100 lbs for Closed Bearings, 85–1100 lbs for Open Bearings.

Composite Linear Bearings - Self-lubricating or ceramic linear/rotary bearing technology, providing high load capability (5000+ psi) along with low friction. Designed as an alternative for linear ball and roller bearings where high loads, wash down, vibration, or contamination may be environmental issues. Self-lubricating bearings do not require any lubrication, ceramic bearings require lubrication at a slightly lower coefficient of friction (0.04-0.08). Outside Diameters: 0.500–6.00", lengths: 0.750–8.00", retaining Hole Diameter: 0.094–0.275".Lee Linear

Composite Linear Bearing Pillow Blocks - Designed to have a low coefficient of friction while maintaining structural integrity. Available in self-lubrication and ceramic models. Resistant to high impact and wear. Shaft diameters between 1/4" to 2".

Composite Linear Bearing Twin Pillow Blocks - Designed for applications that are double the dynamic load carried by a regular composite pillow block. Ideal for contaminate-filled, wash down environments. Also available in ceramic and self-lubricating styles.

Double Length Bearing Pillow Blocks - Available as both opened and closed styles, can be interchanged with the standard Twin Linear Ball Bearing Pillow Blocks and Twin Roller Bearing Pillow Blocks. Both ceramic and self-lubricating bearings are available.


Slide Tables

Basic Slide Tables - Can be set up to be driven by hand, actuator, rack and pinion, gear systems, etc. Does not come with a drive system from manufacturer. Available either with continuous support or end supported. Available in 1/2", 1", and 1-1/2" shafting.

Full Slide Tables - Complete slide system, ready for immediate use and motor mounting. Available with or without full shaft support. Shaft diameters between 1/2" to 1-1/2".

Custom Slide Tables - Lee Linear designs and manufactures slide tables to fit exact specifications.
