QJZ SBLF205-16 2‑Bolt Flange Bearing – 1 in Shaft, Cast Iron Housing

Description

Product Overview

The QJZ SBLF205-16 is a precision‑engineered 2‑bolt flange block bearing designed for demanding power‑transmission tasks. Constructed from high‑grade cast iron, the housing provides exceptional rigidity and resistance to wear, while the insert bearing SB205-16 features a 1 in (25.4 mm) shaft bore that accommodates a wide range of standard shafts. The non‑relubricable design eliminates the need for periodic greasing, reducing downtime and maintenance costs. Each unit is manufactured to tight tolerances, ensuring consistent alignment and load distribution across the flange, which translates to smoother operation and longer service life in heavy‑duty applications.

Technical specifications include a bolt center diameter of 76 mm, a robust 2‑bolt mounting pattern for secure attachment, and a cast‑iron housing that can withstand harsh industrial environments. The bearing is supplied as a complete assembly, ready for installation without additional components. Its compact form factor makes it suitable for retrofitting into existing equipment, while the high‑strength material selection guarantees performance even under fluctuating loads and temperature variations.

Usage

Designed for a broad spectrum of industrial applications, the SBLF205-16 excels in conveyor systems, gearboxes, and machinery where reliable rotational support is critical. Its sturdy cast‑iron housing tolerates vibration and shock, making it ideal for use in manufacturing plants, material handling equipment, and processing lines that operate continuously. The bearing’s non‑relubricable nature is particularly advantageous in environments where dust, contaminants, or limited access make regular lubrication impractical.

Operating temperatures ranging from -20 °C to +120 °C allow the bearing to function in both cold storage facilities and high‑heat processing areas. The 2‑bolt flange design simplifies mounting on shafts with limited space, and the 76 mm bolt center diameter aligns with standard mounting brackets, reducing the need for custom machining. Whether installed in a new system or as a replacement part, the SBLF205-16 delivers consistent torque transmission and minimizes wear on adjacent components.

FAQ

What size shaft can the SBLF205-16 accommodate?

The bearing includes an insert with a 1 in (25.4 mm) bore, which fits standard shafts of that diameter. For applications requiring a different bore size, a compatible sleeve or custom insert can be used.

Is the bearing suitable for high‑temperature environments?

Yes. The cast‑iron housing and bearing materials are rated for continuous operation up to +120 °C, making it appropriate for many industrial heat‑exposed applications.

Can the bearing be installed without additional lubrication?

Absolutely. The SBLF205-16 is a non‑relubricable bearing, meaning it is pre‑filled with a solid lubricant that provides long‑term performance without the need for periodic greasing.

What is the bolt pattern for mounting the bearing?

The flange features a bolt center diameter of 76 mm with a 2‑bolt configuration, compatible with most standard mounting brackets used in industrial equipment.

How does QJZ ensure the quality of each bearing?

Every unit undergoes a series of inspections, including dimensional checks, hardness testing, and load capacity verification, to guarantee that it meets strict performance criteria before leaving the factory.
