Spherical Roller Thrust Bearing 29420

A single mistake in bearing ion can halt the entire production line, costing you not only financial penalties but also professional credibility. The ZWZ 29420 spherical roller thrust bearing is designed to sustain high axial loads and to operate reliably in high-intensity machinery environments. Bejako supplies ready stock with transparent CO/CQ certification and official warranty, enabling you to respond swiftly while maintaining confidence with senior management.

Benefits & Key highlights – Why choose the ZWZ 29420 bearing?

The ZWZ 29420 spherical roller thrust bearing is a dependable choice thanks to its high load capacity, self-aligning capability, and structural design suited for heavy-duty operating conditions in cement plants and steel mills. This product is available in stock with full CO/CQ documentation, fast delivery, and assured on-time supply.

The 29420 ZWZ adopts an E-design configuration with asymmetrical rollers and optimized raceway geometry, ensuring uniform load distribution and mitigating edge stress – a critical advantage in thrust positions under high axial load. The self-aligning structure accommodates shaft misalignment and thermal expansion – conditions commonly found in rotary kilns, crushers, and environments subject to thermal shock.

The typical configuration includes an outer ring of 280 mm, inner ring of 200 mm, width of 48 mm, and weight approximately 8.6–9.3 kg, compliant with industry standards and easily interchangeable. The dynamic load rating reaches C = 656 kN and the static load rating Co = 2,650 kN, with limiting speeds up to 2,200 rpm – meeting the requirements of continuously operating equipment.

Technical specialists value its durability, pressed steel cage design for reduced friction, and reliable performance under proper lubrication and sealing. With transparent CO/CQ certification, rapid delivery capability, and clear warranty policies, ZWZ represents the ideal solution to minimize unplanned downtime and provide plant managers with the technical justification required for board-level approval.

Technical specifications & product features of the ZWZ 29420 bearing

The ZWZ 29420 spherical roller thrust bearing conforms to ISO standard dimensions 200×280×48 mm, fully aligned with the 29240 series specifications, delivering dynamic load C = 656 kN and static load C0 = 2,650 kN.

The product features a pressed steel cage, operating reliably in temperatures ranging from −30°C to +200°C, and achieves a limiting speed of 2,200 rpm under proper oil lubrication. These specifications are consistent with the “E” series spherical roller thrust bearings, validated by comparative technical data from SKF, NTN, and FAG – demonstrating that the ZWZ 29420 provides equivalent geometry and load performance to leading global brands.

Speed limits (reference speed 1,400 rpm limiting speed 2,200 rpm) have been consistently reported by multiple distributors from 2020 to 2024, confirming global reliability and interchangeability in installation and operation. The ZWZ 29420 E is suited for heavy industrial applications such as crushers, rotary kilns, wind turbine shafts – where high axial loads and permissible misalignment must be sustained.

Manufactured in compliance with ISO 199:2005 running accuracy standards, the 29420 series ensures high reliability in interchangeability and smooth operation, helping enterprises avoid costly shutdowns – a crucial safeguard for maintenance engineers entrusted with operational responsibility.

Installation guidelines & application of the ZWZ 29420 spherical roller thrust bearing

Correct installation of the ZWZ 29420 spherical roller thrust bearing is vital to protect equipment from premature failure and to secure optimal performance.

This bearing type is specifically designed for unidirectional heavy axial loads, with additional radial load capacity and misalignment accommodation, making it suitable for cement rotary kilns, crushers, wind turbines, and heavy rolling mills.

Before installation, verify precise dimensions (200×280×48 mm), the correct cage type (pressed steel, designation “E”), and clearance group (CN/CMC) according to operating temperature and fit tolerances.

Mounting design must ensure proper shaft alignment in the load direction, with minor misalignments permissible due to the self-aligning feature of this bearing type.

During installation, avoid excessive force or improper heating methods – common errors such as over-pressing, incorrect mounting tools, or improper seating often cause premature failures.

Furthermore, the correct ion of lubricants, contamination control, and scheduled re-lubrication are key factors in maintaining warranty compliance. When placing orders, customers should clearly specify: part number, clearance group, cage type, CO/CQ certification, warranty conditions, and anti-counterfeit packaging standards.
