Manufacturer & Supplier in India

As a leading industrial distribution specialist, we offer precision-engineered 29300 Series Spherical Thrust Bearings designed to manage severe axial forces while accommodating moderate radial loads. While this series balances high speed with exceptional load capabilities, systems requiring the absolute highest dynamic load ratings under extreme structural strain often transition to the heavier-walled 29400 Spherical Thrust Bearings. Serving critical industrial hubs across India—from the manufacturing centers of Maharashtra and Gujarat to major heavy engineering sectors in Odisha and Jharkhand—we keep your assembly lines running smoothly with deep stock availability and fast dispatch timelines.

The defining internal design of a 29300 spherical thrust bearing features a steep contact angle and a spherical raceway configuration. This specific structural setup allows the unit to act as a self-aligning bearing, guiding the rotating shaft tightly and absorbing immense thrust forces in a single direction. It provides a highly efficient mechanical option for machinery assemblies subjected to shaft deflection, heavy vibration, or structural misalignment, securing rotational accuracy under intense workloads.

Overview

Overview of 29300 Series Spherical Thrust Bearings

Single-Direction Shaft Guidance: Anchors the shaft laterally from one direction to counteract consistent, extreme linear thrust forces.
High Axial Capacity: Optimized line-contact kinematics distribute punishing rolling loads across the specialized spherical tracks.
Low Friction Engineering: Precision-honed internal components limit heat generation during rapid rotation, ensuring optimal oil film distribution.
Design Characteristics

Key Features & Design Characteristics

Integrating a specialized 29300 series bearing brings vital operational protections developed for high-stress industrial drivetrains:

Optimized Roller Guidance Layout

Engineered with asymmetrical spherical rollers running along a spherical housing washer raceway, this configuration safely restrains horizontal drift from one side. This specialized design permits structural shifts without triggering component binding.

Robust Material Engineering

Manufactured using premium-grade, through-hardened carbon-chromium steel to maximize fatigue life. This significantly increases structural stiffness and minimizes outer ring deflection during extreme shocks.

Superior Thermal Stability

Fine-milled tracking zones keep starting torque exceptionally low. By reducing power consumption and thermal buildup, these units run smoothly in high-velocity industrial gear drives and processing equipment.

Where We Supply

Applications & Industries

Our premium 29300 Series bearings are heavily integrated by original equipment manufacturers and maintenance supervisors across India's foundational industrial sectors:

Industrial Gearboxes & Drives

Positioned on primary shafts where intense helical or bevel gear thrust must be managed securely while carrying high loads.

Plastic & Rubber Extruders

Installed directly on extruder screws to absorb the extreme back-pressure generated during high-viscosity material processing.

Centrifugal Pumps & Deep-Well Drilling

Effectively supports heavy vertical or horizontal impeller shafts, keeping the central assembly locked against intense hydraulic feedback.

Blowers and Fan Assemblies

Delivers exceptional running accuracy, thrust management, and vibration containment in large industrial ventilation installations.

Heavy Machinery Cranes & Hoists

Built into crane hooks, marine propulsion drives, and heavy-duty turn-tables to provide structural rigidity in dusty, high-load working conditions.

FAQs

Frequently Asked Questions

A: The EJ suffix signifies an optimized stamped steel cage design that allows for enhanced lubricant flow and low running temperatures. The M suffix features a machined solid brass cage guided by the shaft or rollers, offering ultimate impact resistance and structural integrity under severe shock loads and vibrations.

A: Yes. Unlike standard flat thrust ball bearings, the steep angled design of 29300 spherical roller thrust bearings allows them to handle moderate radial loads simultaneously with heavy axial loads, provided the radial load does not exceed roughly 55% of the axial load.

A: Yes. Because of the large sliding contact area between the rollers and the flange ribs, these bearings require robust lubrication (ideally oil circulation or high-grade grease) to minimize friction and prevent thermal buildup.

A: Yes. We stock the 29328EJ, 29328M, and adjacent models with standard as well as C3 internal clearances to handle extreme thermal expansion in continuous-duty applications.

A: Yes. Every industrial delivery from Swaraj Bearing Company is accompanied by manufacturer certificates of authenticity, testing reports, and official brand tracking parameters to ensure total peace of mind.
