IP-44 Mid BG3 Series In-line

In-line, Mid BG3 Gearing:  All hardened steel, CBN ground Helical gearing! Provides quiet operation, superior shock load resistance compared to competitive models using spur type gears.  Bearings: Premium ball bearings provide efficient torque transfer and good overhung load capacity. Lubricant: High-grade synthetic grease is factory filled to proper level. No expansion bladder required! Shaft seals: Quality NBR rubber, spring set lip type seals provide good wear resistance over a wide temperature range. Housing seals: Machine slip fit "O" rings are used. Leaky compressed gaskets are not used! Mounting: Any angle, any direction, full warranty! No breather or oil plugs are required. Housing: Precision die cast aluminum, coated using an electrocoat process for superior resistance to industrial environments. Third Party: All standard voltages are UL, Cul (CSA), and CE marked.

Mid BG3 Gearing: 100% Hardened steel helical gearing Helical gearing runs quieter and provides greater torque and shock load capacity than competitive spur/helical selectively hardened combinations.
