THOMSON

Thomson Industries, Inc., founded in 1945 and headquartered in Radford, Virginia, USA, is a manufacturer of linear motion components and systems. The company's product portfolio includes ball rails, profile rails, ball carriages, linear ball bearings, shaft support rails, ball screws, and associated accessories such as seals and end blocks. Thomson components are used in applications requiring precise linear positioning, load handling, and motion control across industrial automation, packaging machinery, material handling, and machine tool sectors. The 500 Series ball rails and carriages, such as the 521H30AD+1000 profile rail and 511H25C0D ball carriage, are designed for medium-duty applications with rail sizes ranging from 25 mm to 35 mm, constructed from steel alloy with options for Thin Dense Chrome (TDC) coating or preload specifications like approximate 0.03 C preload. Thomson linear ball bearings, including the SUPER32OPN open bearing, offer dynamic load capacities up to 2,350 lbf and are available with or without wiper seals, using materials such as Delrin and steel. Accessories like the OPNS1000 double-acting seal provide sealing for open bearings, while ball nut end blocks like the 7829547 support ball screw assemblies for 16 mm diameter screws. Thomson also supplies pre-drilled low-profile shaft support rails, such as the LSR-10-PD, in black oxide finish for 5/8-inch shaft diameters. 3G Electric stocks a range of Thomson linear motion components, including mounting rails, carriages, profile rails, bearings, seals, end blocks, and support rails, sourced globally to support maintenance, repair, and operations (MRO) and new equipment builds. These components are specified by engineers and procurement specialists for their dimensional consistency, material specifications, and compatibility with standard rail and shaft sizes. Thomson's product numbering system (e.g., 531MT30, 511H35A1) allows precise identification of rail size, carriage type, and features, facilitating replacement and integration into existing systems. 3G Electric provides logistics support for Thomson products, enabling procurement for facilities worldwide without geographic restrictions.

Common Applications

  • Industrial automation — Thomson 500 Series ball carriages (511H25C0D) used in linear motion axes for pick-and-place systems.
  • Packaging machinery — Thomson profile ball rails (521H30AD+1000) guide conveyor or carton-erecting mechanisms.
  • Material handling — Thomson linear ball bearings (SUPER32OPN) support sliding loads in transfer stations.
  • Machine tool — Thomson ball nut end blocks (7829547) integrate with ball screws for CNC table positioning.
  • Medical equipment — Thomson pre-drilled shaft support rails (LSR-10-PD) mount linear guides in diagnostic scanners.
  • Automated assembly — Thomson double-acting seals (OPNS1000) protect linear bearings in dusty environments.

Frequently asked questions

Common questions about THOMSON from 3G Electric.

What are the key specifications of Thomson 500 Series ball carriages like the 511H25C0D?

The Thomson 500 Series ball carriage model 511H25C0D is designed for 25 mm rail width. It features a steel alloy carriage and roller material, with a Thin Dense Chrome (TDC) finish. This carriage is part of the 500 Series, which is intended for medium-duty linear motion applications. The TDC coating provides corrosion resistance and wear protection. The carriage is compatible with Thomson 500 Series profile rails of the same size.

How do Thomson linear ball bearings like the SUPER32OPN differ from sealed versions?

The Thomson SUPER32OPN is an open linear ball bearing with a 2-inch inside diameter and a dynamic load capacity of 2,350 lbf. It is constructed from Delrin and steel and is supplied without wiper seals, making it suitable for applications where low friction is critical or where external sealing is provided by the housing. Sealed versions include wiper seals to retain lubrication and exclude contaminants, which may increase friction but extend service life in dirty environments.

What is the purpose of the Thomson OPNS1000 double-acting seal?

The Thomson OPNS1000 is a double-acting seal designed for open linear ball bearings, specifically compatible with the Super16OPN bearing. It is made of steel and rubber and fits a 1-inch nominal shaft diameter. This seal prevents ingress of contaminants and retains lubrication, extending bearing life in applications where exposure to dust, debris, or moisture is a concern. It is installed on the bearing housing to provide sealing on both directions of shaft travel.

What rail sizes are available in the Thomson 500 Series profile rails?

Thomson 500 Series profile rails are available in nominal rail sizes including 25 mm, 30 mm, and 35 mm, as indicated by models such as the 521H30AD+1000 (30 mm) and the 521H35AD (35 mm). These rails are made of steel and come in lengths such as 1,000 mm, with multiple rail holes for mounting. The rail width and height vary by size; for example, the 30 mm rail has an overall width of 28 mm and height of 26 mm.

Can Thomson ball nut end blocks like the 7829547 be used with any ball screw lead?

Yes, the Thomson ball nut end block model 7829547 is designed for use with 16 mm diameter ball screws of any lead. It is made of carbon steel and measures 2.99 inches by 1.88 inches by 1.6 inches. This end block provides a mounting interface for the ball nut, allowing integration into linear actuator assemblies. It is compatible with Thomson ball screws and other standard 16 mm diameter screws.

What is the finish on Thomson LSR-10-PD linear shaft support rails?

The Thomson LSR-10-PD linear shaft support rail has a black oxide finish. This rail is pre-drilled for mounting and designed for a 5/8-inch shaft diameter, with a length of 48 inches. The black oxide coating provides mild corrosion resistance and reduces light reflection, making it suitable for applications where aesthetics or reduced glare is desired. The rail is made of steel and is part of Thomson's low-profile shaft support series.
