The LM11749/10 (also known as LM11749/LM11710 or SET1) is a highly versatile, imperial-sized tapered roller bearing measuring 17.462 mm (ID) × 39.878 mm (OD) × 13.843 mm (Width). Designed as a separable cup and cone assembly, it excels at supporting heavy combined radial and axial loads. Widely used in automobile wheel hubs, mining, and metallurgy equipment, we supply B2B manufacturers and distributors with high-quality, factory-direct pricing, flexible customization (5-30 days lead time), and reliable international shipping.
The LM11749/10 Tapered Roller Bearing belongs to the separation type bearing category. It consists of two main detachable parts: the cone assembly (inner ring, tapered rollers, and cage) and the cup (outer ring). During installation, the bearing's internal clearance and axial clearance can be precisely adjusted or pre-loaded to match the specific operating requirements of the machinery. Because the rollers and raceways are in line contact, this bearing can endure heavy radial loads and pure axial loads efficiently.

The engineering geometry of the LM11749/10 provides several crucial advantages for heavy machinery:
Pure Rolling Motion: The design of the tapered rollers ensures that the contact lines between the rollers and the inner/outer raceways all intersect at a single point on the bearing axis, achieving pure rolling motion with minimal friction.
Combined Load Capacity: The angled raceways allow the bearing to manage thrust (axial) loads in one direction simultaneously with heavy radial loads. The larger the contact angle, the higher the axial bearing capacity.
High Rigidity: Built to handle shock and vibration, making it highly reliable in demanding, high-speed applications.
Because of its compact size and exceptional strength, the LM11749/10 is one of the most widely used bearings globally:
Automotive: Wheel hubs, steer axles, drive axles, and gearboxes.
Industrial: Rolling mills, metallurgy, mining machinery, and plastic processing machinery.
Heavy Duty: Hoisting equipment, agricultural tractors, and marine propellers.
We offer a streamlined purchasing process for wholesale buyers and OEMs:
Lead Time: 5–10 work days for in-stock items; 20–30 work days for customized/bulk production runs.
Payment Terms: 30% T/T advance, with the balance paid before delivery. We also support Western Union, PayPal, and L/C for large orders.
Trade Terms: FCA, FOB, CIF, or DDP (Direct Delivery to USA available).
Q1: What does "LM11749/10" mean?
A: It is a combined part number. "LM11749" is the inner cone assembly, and "LM11710" (often shortened to "10") is the outer cup. They are designed to operate together as a matched set.
Q2: Can I buy just the cup or just the cone?
A: Yes, because they are separable, we can supply the cup or cone individually for replacement purposes. However, it is generally recommended to replace them as a complete set to ensure optimal performance and lifespan.
Q3: How do I handle axial loads in both directions?
A: A single tapered roller bearing can only support axial load in one direction. If your application has bi-directional thrust, you must mount two of these bearings in an opposing arrangement (either back-to-back or face-to-face).
