Integral cast iron housing
Made of high-strength grey cast iron via integral casting, dense structure provides better rigidity and anti-vibration performance than aluminum housing for heavy vibrating applications.
Wide-width bronze worm gear set
Wear-resistant tin bronze worm wheel matches carburized precision ground worm; wider meshing surface distributes load evenly for long-term heavy-load operation.
Multi-position pre-tapped mounting holes
Pre-drilled threaded holes on casing support horizontal, vertical and side mounting without extra adapter flanges.
Excellent shock-resistant & heavy-load stability
Solid cast iron structure resists deformation under frequent startup impact, ideal for heavy conveyors and large agitators.
Stable temperature with ample oil storage
Spacious inner cavity holds enough lubricant to disperse heat evenly and control temperature during long full-load operation.
Long service life with anti-aging property
Cast iron features good impact and corrosion resistance to avoid casing crack and oil leakage under dusty & humid conditions, cutting maintenance cost.
Q:Are mounting dimensions identical between cast iron and aluminum NMRV130?
A: Yes, mounting center height and flange size are interchangeable, only net weight differs.
Q: Is extra anti-corrosion coating needed for humid corrosive
A:Standard anti-rust paint is available; customized anti-corrosion coating or blackening treatment is optional for harsh corrosive sites.
Q: Can we get better unit price for repeat bulk orders after sample trial?
A:Sample price is for small trial order; preferential bulk price can be negotiated based on confirmed annual demand.
