Product Overview
Ние можем да произведем плъзгащ лагер EMNLB 28-280, ако имате нужда от плъзгащ лагер EMNLB 28-280, моля, свържете се с нас.
Плъзгащият лагер на двигателя EMNLB 28-280 се използва главно за вертикален двигател, вертикална водна помпа, хоризонтален плъзгащ лагер на мотор и други системи за смазване.
Материал на плъзгащия лагер на двигателя EMNLB 28-280: Бабитова сплав (домашна сплав ZSnSb11Cu6, вносна сплав TEGO STAR738).
Key Benefits
- Slide bearings are produced in ZSnSb11Cu6 Babbitt alloy on the ZQ and DQ frame sizes used on vertical motors, vertical water pumps and horizontal motor lubrication systems.
- Dimensions, material, cage and precision class are confirmed in writing before the order is placed.
- Stock and produced lines are quoted separately so a shutdown can be planned around real dates.
- Non standard sizes can be made to drawing, so a fixed machine envelope is not a dead end.
Who It Is For
Motor rewind shops, power station maintenance departments, pump station operators.
Problems It Solves
Plain bearing shells for older ZQ, DQ and ZQY frames are usually only available from the original machine builder, at a long lead time.

Manufacturing Process
How It Is Made
Forging And Turning
Rings are formed and soft turned to the ring geometry.
Heat Treatment
Through hardening or carburising to the working hardness range.
Grinding And Honing
Raceways and faces ground to the tolerance class ordered.
Assembly And Preservation
Rolling elements and cage assembled, then preserved and packed.
Quality Control
What Is Checked
- Bore, outside diameter and width against the tolerance class ordered
- Radial and axial runout on the finished assembly
- Hardness and surface finish after grinding
- Internal clearance and rotation check before preservation
Certifications. Production runs in strict accordance with the ISO 9001 quality assurance system. Certificate copies for a specific consignment are issued with the shipping documents on request.

Use Guide
Fitting And Service Notes
- Check the shaft and housing seats for size, roundness and damage before opening the packaging.
- Push mounting force through the ring that carries the interference fit, never through the rolling elements.
- Where heat mounting is used, keep the bearing below roughly 120 degrees Celsius and never apply a flame.
- Set clearance or preload as the machine drawing specifies, then fill with the specified lubricant.
- Turn the assembly by hand and listen before the machine is started.
