What SlewPro does

SlewPro, operating under Potesta & Company LLC, is a U.S. custom manufacturer of precision-engineered slewing bearings, slewing drives, and gears founded in 2012 and headquartered in Hudson, Ohio. The company designs and builds components to customer specifications rather than selling from a catalog, offering slewing rings across six series (21, 30, 40, 45, 50, 100) covering single-row ball, cross roller, and triple-row roller configurations, slewing drives (FGE and FWA/WEA worm gear series), and a full gear manufacturing line (helical, internal, spur, worm, splines, sprockets, pulleys) operated through the wholly-owned Rhino Gear subsidiary acquired in 2018. A separate SlimPro sub-brand addresses thin section bearing applications. Underlying technology is a parametric design architecture that allows rapid configuration of bearings and drives to specific load capacities, bore sizes, gear configurations, and duty cycles, supported by in-house application engineering including 3D modeling, 2D drawings, FEA analysis, and material/heat-treatment expertise (SAE 52100, 50Mn, 42CrMo, case-hardening, induction hardening).

The company makes money through one-time custom-component sales priced via quote, with reported 24-hour quote response times and 12-14 week delivery commitments, plus complementary inventory and fulfillment services such as just-in-time delivery, private labeling, and blanket/scheduled-release orders. Go-to-market is exclusively direct-to-OEM sales, targeting small and mid-sized equipment manufacturers underserved by large catalog-bearing suppliers. The customer base spans construction equipment (Loop Belt Industries), robotics (Wolf Robotics), welding/automation (Midwest Engineering Systems), antenna systems (InterTronic Solutions), and marine/tug boat applications, with recent expansion into renewable energy, defense, medical imaging, and precision manufacturing. A December 2025 strategic partnership with United Equipment Accessories (UEA) extends the offering into integrated rotation systems combining slewing bearings with slip rings and hydraulic swivels, positioning the company as a system-level supplier rather than a single-component vendor.

Core offering

SlewPro is a custom manufacturer of precision-engineered slewing rings (bearings), slewing drives, and gears designed and built in the U.S. for small and mid-sized OEMs. The company operates a no-catalog model, configuring components to exact load, dimensional, and duty-cycle requirements rather than supplying standard catalog parts. Complementing its manufacturing operations, SlewPro provides application engineering support (3D models, FEA, technical manuals) and inventory/fulfillment services (just-in-time delivery, blanket orders, private labeling) to OEM customers.

Product overview

SlewPro is a custom manufacturer of precision-engineered rotational components, primarily serving small to mid-sized OEMs. The product portfolio centers on three core product families: (1) Slewing Rings/Bearings available in multiple series (21, 30, 40, 45, 50, 100) covering single-row ball, cross roller, and triple-row roller configurations; (2) Slewing Drives including FGE (enclosed) and FWA/WEA (worm gear) series in single or double worm configurations; and (3) Rhino Gear branded precision gears including helical, internal, spur, worm gears, splines, sprockets, and pulleys acquired in 2018. A complementary sub-brand, SlimPro, offers thin section bearings for space-constrained applications. All products are custom-tailored to customer specifications rather than sold from catalog, with the company providing application engineering support (3D modeling, FEA), CAD files, and inventory management services. SlewPro also partners with United Equipment Accessories (UEA) for integrated rotation systems combining bearings with slip rings and rotary unions.

• United Equipment Accessories (UEA)coreTechnology or Integration · 5 December 2025Strategic partnership uniting SlewPro's turntable bearings with UEA's slip rings and multi-port rotary unions to deliver complete integrated rotation systems. Collaboration enables OEMs to receive a single, engineered rotation assembly combining slewing bearing, hydraulic swivel, and electrical slip ring, designed to the same interface requirements and supported by a unified technical team. Targeted at cranes, renewable energy, material-handling equipment, and heavy industrial machinery.
• Rhino GearcoreStrategic or Co-development PartnerAcquired Rhino Gear to expand product capabilities to include internal and external gears, ring gears, timing pulleys, sprockets, internal and external splines, keyways, custom broached internal shapes, and CNC machined products. Rhino Gear now operates as SlewPro's gear manufacturing division under the SlewPro/Potesta & Company umbrella.
