61852MA 320 mm 260 mm 28 mm Frequently Asked Questions about 61852MA Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Beyond standard alloy steel, CHG Bearing can customize the 61852MA Deep Groove Ball Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
For international ocean and air freight, CHG Bearing packs 61852MA with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
To match diverse operational dynamics, CHG Bearing supplies 61852MA with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
Standard batches of CHG Bearing 61852MA conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
