Regal Rexnord
Gearing Parts & Kits
Regal Rexnord gearing parts and rebuild kits provide the genuine OEM components — gears, pinions, shafts, bearings, seals, shims, and fasteners — required to overhaul and maintain Falk, Browning, Grove Gear, and Hub City gearboxes to original performance specifications.Plant reliability engineers and gearbox repair shops specify genuine Regal Rexnord gear parts to ensure that the material chemistry, heat treatment, and geometric precision of replacement components match the engineering assumptions under which the gearbox was originally designed and rated.Substituting generic aftermarket gears with unknown material properties or tooth profiles introduces a risk profile that includes reduced torque capacity, accelerated wear, increased noise and vibration, and potentially catastrophic gearbox failure — risks that are unacceptable in the critical - drive applications where Falk and Browning gearboxes are typically installed.Our parts and kits are packaged to the specific gearbox model and reduction ratio, including all the wear components replaced during a standard overhaul — bearings, oil seals, gaskets, and shims — in a single part number that simplifies procurement and ensures that no small, critical component is overlooked during the rebuild process.

Trusted by Industry Leaders
OEM Metallurgy & Heat Treatment
Gears and pinions manufactured to the same material specifications and case -depth requirements as the original components, ensuring identical bending - fatigue and surface - durability ratings.
Profile - Ground Tooth Geometry
Replacement gears with the same tooth profile, lead, and surface finish as the original, preserving the gearbox’s noise, vibration, and efficiency characteristics after rebuild.
Complete Overhaul Kits by Gearbox Model
Kits containing all bearings, seals, gaskets, and shims required for a typical overhaul — one part number eliminates the risk of a missing component delaying the rebuild completion.
Application - Specific Bearing Selections
Bearings sourced from the same premium manufacturers specified in the original gearbox, with the internal clearance and cage design required for the specific speed and load conditions.
Technical Support & Rebuild Documentation
Access to the original assembly drawings, bearing setting procedures, and torque specifications that ensure the rebuild is performed to factory standards, not just industry general practice.
Engineered Upgrades Available
Where subsequent engineering analysis has identified opportunities for improvement — upgraded seal materials, higher - capacity bearings, improved lubrication provisions — our rebuild kits can incorporate these enhancements.
The Value of Genuine Regal Rexnord Gearbox Parts vs.Aftermarket
A gearbox that has operated for 15 to 20 years in a steel mill, quarry, or power plant has proven its design — but when it finally requires an overhaul, the quality of the replacement parts determines whether it will run for another 20 years or fail again in two.Aftermarket gears that are not manufactured to the same material and heat - treat standards can suffer from surface spalling or bending - fatigue tooth breakage under loads that the original gear handled reliably.Differences in tooth - profile grinding can increase noise and accelerate bearing wear.Non - OEM seals with incorrect elastomeric compounds can harden or swell in contact with the specified lubricant, leading to leakage and contamination ingress.Genuine Regal Rexnord parts eliminate these risks because they are manufactured to the identical engineering specification as the original components.For a critical - drive gearbox whose failure can shut down an entire production line, the incremental cost of genuine parts is negligible compared to the cost of a repeat failure.
Rebuild vs.Replace: When to Overhaul and When to Upgrade
When a gearbox reaches the end of its first service life, the decision to rebuild or replace requires evaluating the condition of the major components(housings, shaft journals) and considering whether a new gearbox would offer efficiency or reliability improvements not achievable through rebuild.Regal Rexnord’s gearbox service engineers inspect the unit — either on - site or at a Regal Rexnord service center — and provide a detailed condition report with rebuild and replacement options, including cost and lead - time comparisons.In many cases, a rebuild with OEM parts and upgraded seals offers the best combination of cost, lead time, and restoration of original performance.In other cases, replacing a 30 - year - old design with a modern, higher - efficiency gearbox with improved sealing and lubrication reduces energy cost and increases reliability sufficiently to justify the new- unit investment.We provide the unbiased analysis that helps asset owners make the optimal long - term capital decision.
