REGAL REXNORD

Regal Rexnord tire coupling elements are specified by coupling size (e.g., WE2, WE5, WE20, WE70), power rating (from 0.30 HP to 3.65 HP and higher), maximum speed (3,600 to 6,600 RPM), and type (metric or inch). Some elements also list torque rating (e.g., 190 in-lb) and tire outside diameter (e.g., 14 in). The elements are made from natural rubber or polyurethane, with heavy-duty (HD) versions available for higher torque. Operating temperature limits are typically 200°F for natural rubber and 180°F for polyurethane. These specifications help engineers match the element to the application's speed, torque, and misalignment requirements.

Selection involves matching the coupling size to the existing hubs, verifying the maximum speed exceeds the application's operating speed, and ensuring the power or torque rating meets the drive requirements. The element type (metric or inch) must match the hub design. For replacement, use the manufacturer part number (e.g., 7300100) or coupling size and type. Consider environmental factors such as temperature and chemical exposure, which may affect the elastomer choice. If the application involves high shock loads or frequent misalignment, a heavy-duty element may be appropriate. 3G Electric can assist with cross-referencing and selection based on the provided specifications.

Metric and inch designations refer to the dimensional standards of the coupling hubs and elements. Metric elements are manufactured to metric dimensions, while inch elements follow imperial dimensions. They are not interchangeable; the element must match the hub type. For example, a WE20 metric element (MPN 7300100) will not fit an inch hub of the same coupling size. The part numbers often include suffixes like 'HDY' for heavy-duty inch or 'HSU' for heavy-duty metric. When ordering, confirm the hub type from the existing coupling or equipment documentation to ensure compatibility.

Maximum speed ratings for Regal Rexnord tire coupling elements vary by coupling size and element material. Smaller sizes, such as WE2 and WE5, can have maximum speeds up to 6,600 RPM. Larger sizes, such as WE60 and WE70, typically have lower maximum speeds, around 3,600 to 3,800 RPM. These ratings are based on balanced conditions and should not be exceeded. Operating above the rated speed can cause excessive vibration, heat buildup, and premature failure. Always verify the maximum speed for the specific element using the manufacturer's data or the part number specifications.

Regal Rexnord tire coupling elements have temperature limits determined by the elastomer material. Standard natural rubber elements are generally suitable for ambient temperatures up to 200°F (93°C). Polyurethane elements typically have a lower limit, around 180°F (82°C). These limits refer to the ambient temperature around the coupling, not the process temperature. For applications exceeding these limits, alternative materials or heat shields may be required. Consult the manufacturer's engineering data for specific temperature derating factors and to confirm suitability for your operating conditions.

3G Electric supplies Regal Rexnord tire coupling elements from stock and can source additional sizes and configurations. The company provides logistics support for global shipments and can cross-reference manufacturer part numbers to ensure correct replacement. Technical documentation, including specifications and part numbers, is available to assist with selection. For maintenance and repair, 3G Electric can help identify the appropriate element based on coupling size, type, and application requirements. Orders are processed with traceable part numbers to maintain quality and consistency.
