SPHC Carbon Steel TK6204‑102 (98)‑2.5 Bearing Housing with Labyrinth Seal for Belt Conveyor Idler Roller

Meta Description

High-precision TK6204‑102 (98)‑2.5 SPHC carbon steel bearing housing, 2.5mm thick stamped structure with multi-labyrinth dustproof seal. Fit for 6204 bearing, widely used in belt conveyor idler roller mining & industrial conveying systems.

1. Product Overview

The TK6204‑102 (98)‑2.5 bearing housing is a heavy-duty stamped roller housing designed for standard 6204 bearings. Manufactured with premium Baosteel SPHC hot-rolled carbon steel, this 2.5mm thick housing features an optimized multi-stage labyrinth sealing structure, effectively blocking dust, moisture, and slurry intrusion in harsh industrial environments.

Strictly stamped and shaped by precision molds, it delivers uniform thickness, high structural toughness, and excellent concentricity during high-speed operation. It is a core matching part for belt conveyor idler rollers, widely applicable in mining, port, cement, power plant, and bulk material transportation industries.

2. Core Features & Advantages

✅ Premium SPHC Carbon Steel Material

Adopts Baosteel standard SPHC hot-rolled steel plate with stable mechanical properties, tensile strength of 270–410MPa and yield strength above 215MPa. The 2.5mm integrated thickened structure effectively resists extrusion deformation and vibration fatigue, far more durable than ordinary thin steel housings, adapting to long-term high-load operation.

✅ Upgraded Multi-Labyrinth Dustproof & Waterproof Seal

Equipped with TK series non-contact labyrinth sealing system, filled with high-temperature lithium-based grease in the labyrinth gap. It maintains low rotation resistance while forming multiple barrier protection layers, effectively isolating coal dust, sand, rainwater and humid air. Solves common problems of bearing rust, grease failure and short service life of traditional conveyor rollers.

✅ Precision Stamping & Perfect Bearing Fit

Integral one-piece stamping molding process without welding gaps. Strict tolerance control ensures precise matching with 6204 bearings, high concentricity, no eccentric wear during rotation, stable roller operation and low noise, greatly reducing conveyor operating failure rate.

✅ Harsh Environment Adaptability & Long Service Life

Integrates wear resistance, pressure resistance and corrosion resistance. Suitable for outdoor open-air, dusty, humid and other harsh working conditions. Effectively extends the overall service life of conveyor idler rollers and reduces equipment maintenance and replacement costs.

✅ Standardized Size & Easy Installation

Strictly follows TK series industry standard dimensions (102/98 specification, 2.5mm thickness). Fully compatible with mainstream DTII, TD75 series belt conveyor idlers, with strong versatility, plug-and-play installation and high replacement efficiency.
