About the SEW-Eurodrive K99
SEW-Eurodrive gear drives are found in virtually every modern industrial facility — their modular design and worldwide parts network make them highly repairable. R-Series helical inline, K-Series bevel helical, F-Series parallel shaft, and S-Series helical worm units all share common internal components across frame sizes, which means faster diagnosis, faster parts sourcing, and faster turnaround when one fails.
The K99 is a helical bevel, right-angle unit with a rated capacity of 2.2–30 kW and output torque of 3,600–12,600 Nm. Typical operating weight is 150–260 lbs. Mounting configurations include Foot, flange, shaft.
SEW units most commonly fail from seal wear (oil loss leading to bearing starvation), overloading on variable-speed VFD applications without proper derating, and worm gear wear on S-Series units in high-cycle applications.
When your SEW-Eurodrive K99 fails, downtime costs mount fast. Our standard rebuild turnaround is 8–14 business days with free freight both directions. Emergency 24–72 hour service is available. We publish pricing before teardown — no surprises.

Why Repair Your SEW-Eurodrive K99 Instead of Replacing It?
- SEW's modular architecture means most internal components are interchangeable across frame sizes — we stock common gears, bearings, and seals for rapid turnaround.
- Aluminum-housed smaller units (R07–R47) are often more cost-effective to replace, but larger cast iron units (R67–R107, K69–K109) are almost always worth rebuilding.
- SEW's worldwide distribution means parts are rarely on long backorder — typical rebuild turnaround is 5–10 business days.
Frequently Asked Questions — SEW-Eurodrive K99
What causes SEW-Eurodrive gear drive failure?
The most common failure mode is seal wear leading to oil loss and bearing starvation — especially on units running in dusty or wet environments. VFD-driven units running at low speeds without adequate cooling are also prone to premature bearing failure. Call (641) 519-6270 for a free teardown quote.
Can SEW-Eurodrive gearmotors be repaired without the motor?
Yes — we regularly separate the gear head from the motor and rebuild just the gear unit. We can also match replacement motors if needed. The gear unit and motor are independently repairable. Call (641) 519-6270 for options.
How much does SEW-Eurodrive repair cost?
R-Series and K-Series rebuilds typically run $800–6,000 depending on frame size and damage. Larger F-Series and industrial units run $3,000–15,000+. We publish pricing before teardown. Call (641) 519-6270.
Do you stock SEW-Eurodrive parts?
We maintain inventory of common SEW bearings, seals, and gear sets for R37–R97 and K39–K89 frames. For less common models we source from SEW's distribution network, typically 2–5 business days. Call (641) 519-6270.
