MAPLE ACE SA209-28 Insert Bearing 1-3/4″ Bore, Spherical OD with Eccentric Locking Collar and Lubrication Hole

Description

Product Overview

The MAPLE ACE SA209-28 insert bearing is engineered for demanding power transmission applications where precision, durability, and performance are paramount. Featuring a 1-3/4″ bore, the bearing accommodates a wide range of shaft sizes while delivering a spherical outer diameter (OD) that ensures optimal alignment and load distribution. The eccentric locking collar provides a secure, adjustable fit, allowing for easy installation and maintenance without sacrificing rigidity. Integrated lubrication holes enable targeted oiling, reducing friction and extending service intervals. Constructed from high‑grade steel, the bearing offers resistance to wear, corrosion, and temperature extremes, making it suitable for heavy‑duty machinery, conveyors, and gearboxes operating under continuous load. The design balances high speed capability with low vibration, delivering smooth operation and minimizing noise in both industrial and OEM environments.

Usage

This insert bearing excels in a variety of settings, from manufacturing plants and material handling systems to agricultural equipment and marine applications. Its robust construction tolerates harsh climates, including high humidity, dust, and temperature fluctuations, ensuring reliable performance in outdoor and indoor installations alike. Engineers and maintenance technicians appreciate the ease of retrofitting existing shafts, as the eccentric locking collar adapts to minor misalignments while maintaining precise radial positioning. The lubrication hole design supports routine greasing schedules, which is essential for equipment that operates continuously or under variable loads. Whether used in high‑speed spindle drives, heavy‑duty conveyor rollers, or custom‑built gear assemblies, the SA209-28 provides consistent torque transmission and reduces downtime caused by bearing wear or failure.

FAQ

What shaft sizes are compatible with the SA209-28 insert bearing?

The bearing is designed for a 1-3/4″ bore, accommodating shafts ranging from 1.70″ to 1.80″ in diameter, allowing for slight variations while maintaining a secure fit.

Can the bearing be used in high‑temperature environments?

Yes, the steel alloy and heat‑treatment process enable operation in temperatures up to 200°F (93°C) without loss of performance.

How often should the lubrication hole be serviced?

For continuous‑run applications, we recommend greasing the lubrication hole every 500 operating hours, or more frequently under extreme load conditions.

Is the eccentric locking collar adjustable after installation?

Absolutely. The collar can be repositioned to fine‑tune bearing alignment, making it ideal for applications where shaft deflection may occur over time.
