Key Features:

1. Single-row tapered roller design for combined radial and one-direction axial loads — supports heavy service loads with stable running.
2. Cone 525 and cup 522 separable — simplifies installation, inspection, and replacement without disturbing the assembly.
3. Hardened bearing-steel rings and rollers — resist wear and fatigue for longer service intervals.
4. Robust steel cage — maintains roller spacing at high RPM and under shock, preventing skew and uneven wear.
5. Tight tolerances — ensure precise fit and alignment, improving stability and reducing rework time.

FAQ:

Q1: What type is this bearing?
A1: A single-row tapered roller bearing set (cone and cup set).

Q2: What loads can it handle?
A2: Heavy radial loads and axial (thrust) loads in one direction; greater contact angle increases axial capacity.

Q3: What are typical applications?
A3: Gearboxes, axles, transmissions, heavy machinery, and other assemblies needing combined load support.

Q4: What is the lead time after placing an order?
A4: We stock many common roller and ball bearings (e.g., 535 sets of 5595/5535, 498 sets of 497-493, 369 sets of MR16257-2RS). If your order is within stock, lead time is within 3 working days.
