1. Product Overview

M802048/11, HI-CAP M802048-N and M802048-M802011 are fully interchangeable inch single row separable tapered roller bearings under M802000 series, unified core mounting dimension d=41.275mm, D=82.55mm, T=26.543mm, consistent inner cone M802048 matched with outer cup M802011.

Model suffix technical difference explanation:

1. M802048-M802011 / M802048/11: Standard general base version, stamped steel cage, conventional integral quenching heat treatment, cost-effective for intermittent medium-load truck and construction equipment working conditions.
2. HI-CAP M802048-N: HI-CAP heavy load upgraded grade; N reinforced surface hardening process, optimized logarithmic roller contact curve, thicker roller body and improved surface finish, stronger wear resistance, anti-impact and high temperature durability, lower running noise, extended service life under 24h continuous heavy shock load.

Open split cone & cup independent structure, inner cone assembly (inner ring + tapered rollers + cage) and outer cup can be disassembled separately, convenient independent component replacement, preload adjustment and on-site maintenance of truck differential, vehicle drive axles and medium construction machinery reduction assemblies. All rings and rolling elements adopt through-hardened GCr15 chrome bearing steel, strict roller sorting and ultra-precision raceway superfinishing, stable low-vibration rotation under long-term alternating heavy radial & axial combined impact load. Widely matched for heavy-duty truck differential, agricultural tractors, light loaders and mining transport vehicle axle systems.

3. Core Advantages

1. Three model numbers share fully interchangeable installation dimensions, customers can select cost-control standard M802048/11 for intermittent working or reinforced HI-CAP M802048-N for long-term continuous heavy-load truck and mining equipment.
2. Standard inch compact width design, balanced radial-axial combined load capacity, perfectly fit narrow housing layout of truck differential and vehicle drive axle assemblies.
3. Fully separable independent cone & cup split structure, damaged inner cone or outer cup can be replaced separately without overall disassembly of transmission housing, greatly reduce vehicle maintenance downtime and spare part procurement cost.
4. Precision mirror superfinished tapered raceway + logarithmic optimized roller contact curve, uniform stress distribution on roller contact surface, effectively reduce edge stress concentration and delay raceway peeling failure.
5. Dual cage configuration options: cost-effective stamped steel cage for general intermittent medium load; solid brass cage anti-deformation for non-stop high-temperature harsh transportation production lines.
6. Full customizable service support: C3 enlarged radial clearance, P5/P6 high precision grade, OEM laser marking, special high-temperature anti-oxidation grease filling, neutral export brand packaging.
7. HI-CAP M802048-N exclusive N surface strengthening heat treatment process, uniform internal material hardness and structural strength, reduce abnormal wear failure rate of vehicle axle bearings.
8. Open unsealed design supports built-in gearbox circulating oil bath lubrication, adapt to differential internal abundant circulating lubricating oil system, realize long-term stable continuous operation.
