7318 BM CX Angular Contact Ball Bearing 90x190x43

Technical Specifications & Design

The 7318 BM CX is a single-row angular contact ball bearing engineered to support combined radial and axial loads in one direction. It is frequently searched online using phrases like „7318 BM CX bearing”, „7318 BM CX 90x190x43”, or „single row angular contact bearing 90x190x43”.

Key specifications:

• Bore (inner diameter): 90 mm

• Outside diameter: 190 mm

• Width (thickness): 43 mm

• Contact angle: typically ~ 40° for angular contact series

• Cage material: brass or machined bronze in many designs (e.g. Rollway)

• Bearing steel material: 52100 or equivalent high-carbon chrome steel

• Load ratings: e.g. for Rollway 7318 BM — dynamic ~156 kN, static ~135 kN

• Speed limits: e.g. ~2800 rpm (grease) / 3800 rpm (oil) in some catalogs

This 7318 BM CX bearing is ideally designed for high-precision machinery, industrial drives, gearboxes, spindle systems, and other applications demanding robust radial and axial load handling.

Applications & Industrial Uses

• Used in industrial gearboxes, machine tool spindles, precision drives, and robotic systems where a combination of radial and axial loads is present.

• Suitable for setups requiring compact footprint but high load capacity, where the search phrase “7318 BM CX bearing 90x190x43” is often used by technical buyers.

• Can be paired or used in duplex sets (back-to-back or face-to-face arrangements) in high-demand systems for improved axial stiffness.

• As a variant of BM / CX line, it may be compatible or substitutable with other angular contact bearings of similar dimension sets (e.g. BECBM, BM/UL in catalogs).

This type of bearing is particularly favored where precision, stiffness, and longevity are required — e.g. in automation lines, aerospace actuation, high-speed spindles.

Advantages & Performance Highlights

• Combined load capability: Can handle radial and axial forces in one direction, thanks to angular contact geometry.

• High load ratings: The bearing supports substantial load capacities — e.g. 156 kN dynamic and 135 kN static in some catalogs for 7318 BM variants. MROSupply

• Precision construction: Tight tolerances, stable raceways, minimal runout — helpful where vibration and alignment matter.

• Durability: High-grade steel resists fatigue; proper cage design ensures stable ball guidance.

• Flexibility in mounting: Can be used standalone or in paired configurations for enhanced axial load performance.

• Compatibility in global searches: The inclusion of “7318 BM CX”, “90x190x43 angular contact bearing” and related terms helps align with buyer search intent.

These benefits are directly aligned with search patterns like “7318 BM CX angular contact bearing”, “angular contact bearing 90x190x43”, and “7318 BM CX” seen in parts databases.

FAQ — Common Buyer Questions

Q1: What does “BM CX” mean in the bearing designation?
A: “BM” generally refers to a variant or series type (cage or design) and “CX” often denotes a special tolerance, precision class, or internal design variant used by manufacturers.

Q2: Does this bearing carry axial loads?
A: Yes — as an angular contact bearing, it is designed to carry both radial and axial loads (in one direction). The contact angle (e.g. 40°) determines the balance between radial vs axial load capacity.

Q3: Can it be used in pairs for bi-directional axial load?
A: Yes — many installations use matched pairs (back-to-back or face-to-face) to allow axial load in both directions and greater rigidity.

Q4: What is the maximum speed for 7318 BM CX?
A: Speed depends on lubrication, internal clearance, and specific manufacturer specs; for example, a Rollway 7318 BM variant is rated ~2800 rpm (grease) / 3800 rpm (oil).

Q5: Is this product available for fast dispatch?
A: Yes — we stock it at Warehouse & Store: Lublin, ul. Smoluchowskiego 1, building 4, and ensure 24h delivery across Poland.
