THOMSON
Frequently asked questions
Common questions about THOMSON from 3G Electric.
What is the difference between Thomson closed linear ball bearings and Thomson polymer bushings?
Thomson closed linear ball bearings, such as the SUPER12, use recirculating ball elements to provide low-friction linear motion and are rated for higher dynamic loads, for example 600 lbf for the SUPER12. They are typically used in applications requiring precise guidance and moderate to high load capacity. Thomson polymer bushings, such as the PLM series, are closed linear plain bearings with a self-lubricating polymer liner and polymer shell. They are designed for low-load and low-speed applications and do not require external lubrication. The choice depends on load, speed, and environmental conditions. Ball bearings generally offer higher load capacity and stiffness, while polymer bushings are simpler, lighter, and maintenance-free in light-duty use.
What sizes of Thomson polymer bushings are available through 3G Electric?
3G Electric supplies Thomson polymer bushings in a range of inside diameters, including 3/8 inch (PLM08), 1/2 inch (PLM12), 1 inch (PLM25), 1-5/8 inch (PLM40), and 2 inches (PLM50). Corresponding lengths vary by size; for example, the PLM08 has a 1-inch length, while the PLM50 has a 3-7/8-inch length. These bushings are part of the closed linear plain bearing family and feature a self-lubricating polymer liner and polymer shell. They are intended for low-load and low-speed linear motion applications. Additional sizes may be available; buyers can inquire with 3G Electric for specific part numbers and dimensions.
Are Thomson linear bearings suitable for high-speed applications?
Thomson linear ball bearings, such as the SUPER12, are generally suitable for higher-speed applications compared to polymer bushings. The recirculating ball design reduces friction and allows for faster linear motion, although actual speed limits depend on load, lubrication, and installation. Thomson polymer bushings, like the PLM series, are specifically designed for low-load and low-speed applications. For high-speed requirements, ball bearing types are typically recommended. Buyers should consult the product specifications for maximum speed ratings and consider factors such as acceleration, duty cycle, and environmental conditions. 3G Electric can provide technical data for specific Thomson part numbers to assist in selection.
What materials are used in Thomson SUPER12 linear ball bearings?
The Thomson SUPER12 closed linear ball bearing is constructed from Delrin and steel. The outer sleeve or housing is made of Delrin, a thermoplastic material, while the ball elements and inner components are steel. This combination provides a balance of light weight, corrosion resistance, and load-bearing capability. The bearing has a 3/4-inch inside diameter and a 600 lbf dynamic load capacity. It is supplied without wiper seals, meaning it does not include integral wiper seals for contaminant exclusion. For applications requiring wiper seals, alternative Thomson part numbers or additional sealing solutions may be necessary. 3G Electric lists the SUPER12 and related components with material and specification details.
Can Thomson polymer bushings be used without lubrication?
Yes, Thomson polymer bushings in the PLM series are self-lubricating. They use a polymer liner and polymer shell that provide low friction without the need for external lubricants. This makes them suitable for maintenance-free operation in low-load and low-speed applications. However, the self-lubricating property does not imply suitability for all environments; factors such as temperature, contamination, and duty cycle can affect performance. For high-load or high-speed conditions, other Thomson bearing types may be more appropriate. 3G Electric supplies these bushings for applications such as packaging equipment and laboratory instruments where lubrication is impractical or undesirable.
How does 3G Electric support Thomson product sourcing?
3G Electric supplies Thomson linear bearings and rail systems as part of its industrial equipment distribution. The company offers a catalog of Thomson SKUs, including closed linear ball bearings and polymer bushings, with specifications such as inside diameter, load capacity, and materials. Buyers can request quotes for specific part numbers, and 3G Electric provides logistics support for global shipping. The company serves plant engineers, maintenance managers, and procurement specialists by facilitating access to Thomson components and handling order processing. 3G Electric does not manufacture Thomson products; it distributes them. For technical selection, customers can refer to the product data provided or contact 3G Electric for assistance with part number identification.
