Agricultural Machinery Bearings：SNU530

Description

Basic Information

Model Interpretation: SNU530 indicates a split vertical plummer block housing (SNU), medium load class (5), and shaft diameter 30mm (30). Split design allows bolted assembly (4×M24) for maintenance-free bearing replacement.

Dimensions: Center height 160mm, total length 530mm, compatible with 22230/23230 spherical roller bearings (OD 270mm).

Materials: Gray cast iron (HT250) or ductile iron (QT450), black powder coating.

Sealing: Double-lip rubber + labyrinth seal (IP65), optional felt/U-type seals.

Standards: GB/T 7813 & ISO 113, weight 46kg (with locating rings & oil seals).

Product Advantage

Split Design for Efficiency

Patented split structure reduces maintenance time by 70% (vs. integral housings), ideal for conveyors and crushers requiring quick bearing replacement.

Heavy-Duty Performance

Ductile iron (450MPa tensile strength) supports 35% higher radial load than SN series, suitable for 24/7 mining operations.Optimized oil grooves extend bearing life to 8,000 hours (vs. 5,000h industry average).

Environmental Resilience

Triple-seal system reduces contamination by 92% in dusty conditions, extending maintenance intervals from 3 to 12 months.Salt spray resistance >500 hours, 2x longer than standard coatings in coastal/moist environments.

Universal Compatibility

ISO 113-compliant design fits NSK/SKF equivalents (SN530/SNU530), with ±2mm hole adjustment for retrofitting 90% of industrial equipment.

Product Application

Industrial Conveying

• Belt conveyor drive rollers (port coal lines, 100,000T/day capacity), split design avoids system disassembly.
• Bucket elevator heads (abrasive materials like limestone), ductile iron resists 5+ years of impact.

Mining & Metallurgy

• Vibrating screen supports (8-12mm amplitude), labyrinth seals block ore dust.
• Blast furnace feeders (80℃ operation), grease lubrication prevents oil line blockage.

Environmental & Municipal

• Wastewater aerator fans (corrosive/moist), optional stainless seals last 3+ years.
• Waste crushers (1,500N·m torque), heavy-duty design withstands foreign object impacts.
