Heavy-Duty Integrated Round Flange Linear Ball Bushing

Dual-Sided Synthetic Rubber Lip Seals Flanged Linear Bushing

Product Description

Product Overview

The LMF80UU Round Flanged Linear Bearing is built to deliver smooth, high-capacity linear motion along large-diameter 80 mm shafts. It is engineered specifically for heavy industrial machinery and structural automation guide rails where maximum structural stiffness, flawless axial alignment, and high load distribution are essential parameters.

Key Advantages

Heavy-duty integrated round flange with 6 counterbored mounting holes ensuring a rigid, rock-solid surface connection.
Multi-row steel ball recirculating matrix distributing heavy radial loads evenly across the shaft horizon.
Dual-sided synthetic rubber lip seals providing ultimate lockout against abrasive workshop dust and fluid splashing.
Precision-hardened carbon steel casing minimizing structural deflection and maintaining tight runout limits under load.
Streamlined bolt-on structural integration completely eliminating the need for separate outer housing blocks or snap rings.

Frequently Asked Questions

Q1: Can you provide custom bearings?

Yes, we support comprehensive OEM/ODM manufacturing parameters. We can manufacture stainless steel configurations (LMF80-MG), supply extended long-body layouts (LMF80LUU), or configure specialized high-temperature steel cages tailored to your blueprints.

Q2: What is the main structural advantage of the round flange (LMF) over the square flange (LMK) design?

The round flange configuration features more mounting holes (6 holes for large sizes like the LMF80UU compared to 4 holes on square configurations). This optimizes load distribution symmetrically around the shaft axis, drastically boosting resistance against bending moments.

Q3: What shaft tolerances do you recommend pairing with the LMF80UU bearing?

To achieve optimal linear accuracy and prevent premature ball tracking wear, we highly recommend running this bearing on high-precision induction-hardened linear shafts (g6 or h6 tolerance class) with a minimum surface hardness of HRC60–64.

Q4: Do you support bulk orders?

Yes, we maintain solid raw material inventory buffers for heavy metric linear guide arrays to fulfill large-volume wholesale contracts, providing heavy-duty export boxes and direct-factory volume pricing tier discounts.
