Shaft 190mm LOE238-N-BL-L Split Plummer Block Housing 190x820x485mm

1. Product Overview

LOE238-N-BL is heavy-duty split plummer block bearing housing belonging to LOE-N series floating bearing seat, specially designed to match spherical roller bearing 22238-MB, applicable for shaft diameter d=190mm. Split two-piece cast iron structure enables fast on-site installation and disassembly without removing large transmission components from the shaft.

Suffix code definition:

• N: Standard oil circulation lubrication structure, built-in oil storage tank and oil level observation window, suitable for long-time continuous running equipment.
• BL: Floating type housing structure, allows slight axial displacement of inner bearing to compensate shaft thermal expansion, avoid extra axial stress damage to rolling elements.

Integrated supporting accessories matched together: lock nut KM38, tab washer MB38, standard pre-filled initial lubricating oil 7.2L, built-in oil level height limit range 70–100mm. Thick wall high-strength cast iron housing with internal reinforcement rib, strong anti-vibration and impact resistance, stable supporting performance under heavy alternating radial load. Widely used for large mining belt conveyors, metallurgical rolling equipment, heavy industrial gearboxes and large rotary kiln auxiliary transmission shafts.

2. Technical Specifications

Complete installation drawings, lubrication maintenance guide and heavy vibration durability test reports can be provided upon customer request.

3. Core Advantages

1. Split two-piece housing design, no need to disassemble whole transmission equipment during bearing replacement, greatly shorten maintenance downtime of large mining conveyor lines.
2. BL floating type structural design, automatically absorb shaft thermal expansion axial elongation, eliminate bearing axial clamping force, effectively extend service life of matched 22238 spherical roller bearing.
3. Built-in independent oil storage tank + visual oil level window, convenient real-time check of lubricant volume, reduce frequent shutdown refueling frequency for 24h continuous mining production lines.
4. Thick wall cast iron with internal reinforcing rib structure, high rigidity and strong anti-shock performance, stable operation under long-time heavy impact load of mining conveying equipment.
5. Multi-stage labyrinth integrated dust-proof structure, effectively block mineral dust, metal abrasive debris and splashed lubricating oil, adapt to harsh open-air mining working environment.
6. Full customizable service support: C3 clearance matched bearing assembly, high temperature resistant lubricant filling, OEM laser marking on housing surface, neutral export wooden case packaging.
7. Complete matched standard locking nut and tab washer, one-stop supporting supply, save customer separate procurement cost of auxiliary fastening parts.
8. Standard oil bath circulating lubrication system, can connect external forced oil supply pipeline for ultra-long continuous high-speed heavy load working conditions.
