Agricultural machinery works directly immersed in wet clay, abrasive field slurry, and rock impacts during planting and harvest seasons. Here is how BMT Impex guarantees field endurance.
Triple-lip (3-lip) rubber contact seals reinforced with steel trash guard flingers deflect thick wet mud and crop stalks away from the internal raceways.
Heavy-duty ductile iron cast housings (FCD) paired with high-impact GCr15 vacuum-degassed bearing steel absorb severe subsurface rock shocks without ring fracture.
Factory packed with high-tack, water-repellent calcium-sulfonate grease with anti-corrosion rust inhibitors, protecting bearings even during 6-month off-season outdoor storage.
Spherical outer diameter inserts self-align smoothly inside cast pillow block and flange units, accommodating structural frame twisting during rough furrow tilling.
Precision broached square bore (1", 1-1/8", 1-1/4", 1-1/2") and hex bore designs lock positively onto agricultural gang shafts without slippage.
We maintain locked seasonal inventory of all popular disc harrow, rotavator, and combine bearings for JIT dispatch to agri implement OEMs nationwide.
Engineered for disc harrows, rotary tillers, combine harvest drums, and PTO drive units.
Specialized heavy-duty ball and roller bearings with square, round, or hex bore. Triple-lip contact seals and external steel trash guards prevent mud ingress in heavy tillage.
UCP, UCF, UCFL, and UCFC 200/300 series cast iron and ductile iron housed units. Self-aligning insert ball bearings with grub screw or eccentric locking collar.
High-torque deep groove ball bearings (6200/6300 2RS C3) and heavy taper roller bearings (30200/32200) for rotary tiller side gearboxes and combine threshing rotors.

Every agricultural bearing batch is tested at our in-house facility to guarantee robust seal barrier integrity, high shock toughness, and precise bore tolerances.
Rotating seal chambers are evaluated in sandy mud slurry tanks to verify 100% barrier against fine abrasive particles.
Core and surface hardness verified on digital Rockwell testers to eliminate plastic deformation under heavy tillage shocks.
100% plug gauge inspection confirms accurate dimensional fit onto agricultural implement gang bolts and drive shafts.
Specialized calcium grease adhesion tested under high-pressure water spray to prevent grease leaching during field washing.

Disc harrows operate submerged in wet mud, sand, and crop residue. Standard single-lip seals fail rapidly when abrasive silt penetrates past the contact edge. Our triple-lip (3-lip) nitrile seals combined with an external stamped steel trash guard flinger create multiple physical barriers to extend bearing life by over 300% in heavy black cotton and clay soils.
Yes. All BMTV2 and WBT disc harrow, rotavator, and pillow block bearings are manufactured to standard agricultural industry dimensions, matching OEM specifications across Mahindra, Sonalika, Shaktiman, Fieldking, John Deere, and New Holland implements.
Yes. All commercial consignments include full 18% GST B2B tax invoices with e-way bills for seamless 100% Input Tax Credit (ITC), accompanied by Mill Test Certificates (MTC 3.1) and Certificate of Conformance upon request.
We stock high volumes ahead of planting and harvest seasons. Dispatches take place within 24 to 48 hours to major agricultural machinery manufacturing belts (Ludhiana, Karnal, Rajkot, Indore, Pune, Coimbatore, Hyderabad) in 2 to 3 business days.
