Stop Construction Delays with Timken 21316 Self-Aligning Roller Bearings
Construction and mining operations lose thousands daily when equipment fails due to bearing issues. Misalignment in heavy machinery like excavators and loaders often leads to premature bearing wear, while sourcing genuine replacement parts from multiple suppliers wastes valuable time. Many buyers face the dilemma of choosing between long lead times for authentic bearings or risky counterfeits that fail under heavy loads.
Timken 21316: The Reliable Solution for Heavy-Duty Applications
As an official Timken distributor, we offer the Timken 21316 self-aligning roller bearing—specifically engineered to handle radial loads and misalignment in construction machinery. With dimensions 80x170x39mm and precision ratings from P0 to P2, this bearing delivers consistent performance in harsh environments. Our one-stop procurement service eliminates the need to coordinate with multiple suppliers, ensuring your project stays on schedule with genuine parts delivered when you need them.
Engineered for the Toughest Construction Environments
This self-aligning roller bearing excels in applications with heavy radial loads and moderate axial loads, common in construction equipment like excavator swing mechanisms and loader arm pivots. Its double-row design and spherical outer ring allow for up to 2 degrees of misalignment, reducing stress on shafts and housings. Constructed from high-grade bearing steel, it withstands the dust, vibration, and temperature fluctuations typical of construction and mining sites, minimizing unplanned downtime.
Technical Details That Maximize Equipment Uptime
The Timken 21316’s precision ratings (P0-P2) ensure optimal performance across different application requirements—P2 for high-precision machinery and P0 for general industrial use. Clearance options (C0, C3, C4) allow customization based on operating conditions: C3 and C4 clearances accommodate thermal expansion in high-temperature environments, while C0 suits standard operating conditions. The unseparated design simplifies installation and maintenance, critical for field service teams working under tight deadlines. With a focus on durability, this bearing’s roller geometry distributes load evenly, extending service life in heavy-duty cycles.
Why Genuine Timken Bearings Reduce Total Cost of Ownership
Counterfeit bearings may cost less upfront, but they often fail within months, leading to expensive equipment repairs, production delays, and safety risks. Genuine Timken bearings, like the 21316, undergo rigorous testing to meet ISO 9001 standards, ensuring reliable performance and longer service intervals. Our unified quality inspection system verifies every bearing before shipment, so you avoid the hidden costs of premature failure. For construction and mining operations, where downtime can cost $10,000 or more per day, investing in genuine bearings reduces long-term expenses and protects your equipment investment.
