[2-Pack] SA207-23 – Insert Bearing – 1-7/16 in Bore – 2.835 in Outer Diameter – 1.531 in Width – 0.669 in Outer Ring Width – Eccentric Mounting Collar, Non-Relubricable

Description

Product Overview

The QJZ SA207-23 insert bearing is engineered to meet the rigorous demands of modern industrial power transmission equipment. Constructed from high‑grade alloy steel, the bearing features a precision‑machined inner bore of 1‑7/16 inches (36.5 mm) that accommodates a wide range of shaft sizes while maintaining tight tolerances for minimal runout. The outer diameter measures 2.835 inches (72 mm) and the width is 1.531 inches (38.9 mm), providing a robust load‑bearing surface that distributes forces evenly across the bearing raceways. The eccentric mounting collar, a distinctive design element, allows for fine‑tuned alignment during installation, reducing stress concentrations and extending service life. This model is non‑relubricable, meaning it is supplied pre‑lubricated with a high‑performance solid film that eliminates the need for periodic oil or grease applications, simplifying maintenance schedules and reducing downtime.

Each bearing is supplied as a 2‑Pack, ensuring that replacement units are readily available for critical applications where redundancy is essential. The weight of each unit is 10.88 ounces, making it lightweight enough for easy handling yet sturdy enough to withstand the high‑impact forces typical of heavy machinery. The bearing’s outer ring width of 0.669 inches (17 mm) contributes to its rigidity, while the overall design promotes efficient heat dissipation, preventing overheating in continuous‑run environments. The product has earned a Best Sellers Rank of #71 in the Insert Bearings category, reflecting its popularity among engineers and maintenance professionals who value reliability and performance.

Usage

Designed for a broad spectrum of industrial applications, the SA207-23 insert bearing excels in environments where precision, durability, and ease of installation are paramount. It is ideally suited for use in gearboxes, motor assemblies, conveyor systems, and heavy‑duty pumps where shaft alignment is critical to prevent premature wear. The bearing’s non‑relubricable nature makes it an excellent choice for sealed or hard‑to‑reach locations, such as underwater pumps, high‑temperature furnaces, and aerospace components where traditional lubrication methods are impractical.

Installation is straightforward thanks to the eccentric mounting collar, which permits slight adjustments to achieve perfect concentricity with the shaft and housing. This feature reduces the need for additional shims or custom machining, saving both time and cost during assembly. The bearing’s dimensions are compatible with standard mounting brackets, allowing it to be retrofitted into existing equipment without extensive redesign. Its robust construction also makes it suitable for high‑speed applications, where rotational stability and vibration damping are essential for maintaining operational efficiency.

Maintenance crews appreciate the bearing’s low‑maintenance profile. Because it is supplied with a solid‑film lubricant, there is no requirement for periodic oil changes or grease re‑application, which can be especially advantageous in remote or hazardous locations. The bearing’s resistance to contamination from dust, moisture, and chemicals further enhances its reliability in harsh industrial settings, ensuring consistent performance over extended service intervals.

FAQ

What does non‑relubricable mean for this bearing?

Non‑relubricable indicates that the bearing comes pre‑lubricated with a solid‑film lubricant that does not require additional oil or grease during its service life. This reduces maintenance effort and prevents contamination in sealed environments.

Can the eccentric mounting collar be adjusted after installation?

Yes, the eccentric collar is designed to allow slight adjustments during the initial installation to achieve perfect concentricity. Once the bearing is secured, the position remains stable under normal operating conditions.

Is this bearing suitable for high‑speed applications?

Absolutely. The bearing’s precision geometry and high‑quality steel material enable it to operate at high rotational speeds while maintaining stability and low vibration levels.

What is the recommended method for removing the bearing if replacement is needed?

We recommend using a calibrated puller or a bearing removal tool that matches the outer diameter of the bearing. Apply even pressure to avoid damaging the housing or shaft, and follow the removal instructions provided in the technical manual.

Do you offer custom sizes or modifications for this bearing?

QJZ provides engineering assistance for custom bearing solutions. Contact our sales team with your specific dimensions or performance requirements, and we will work with you to develop a tailored product.
