Needle Roller and Cage Assembly TAF293820 IKO

The IKO TAF293820 is a high-precision thrust needle roller bearing engineered for axial load-bearing applications in compact mechanical systems. Fully compliant with ISO 3030 and JIS B 1516 standards, this IKO thrust bearing features a slim design, high axial load capacity, and low friction, making it a top choice for automotive, industrial machinery, precision tools, and aerospace accessories. As a premium IKO bearing model, it excels in space-constrained environments where reliable axial force transmission and long service life are critical.

1. Detailed Dimensional Parameters (SEO: TAF293820 bearing dimensions, IKO TAF293820 specs): The IKO TAF293820 has an inner diameter (d) of 29 mm, outer diameter (D) of 38 mm, and width (B) of 20 mm. Minimum chamfer size (rₘᵢₙ) is 0.3 mm, single weight is 0.032 kg. Tolerance grade is P0 (ISO 492), with inner/outer diameter tolerance of IT6 and width tolerance of IT7. Basic dynamic axial load rating is 28.5 kN, basic static axial load rating is 52.8 kN, and limiting speed (grease lubrication) is 8,500 r/min, optimized for high-axial-load, medium-speed scenarios.

2. Specific Material Description (SEO: thrust needle roller bearing materials, IKO bearing material): Raceway and needle rollers are made of high-carbon chromium bearing steel (AISI 52100/GCr15), refined by vacuum degassing to reduce non-metallic inclusions. After precision heat treatment, they reach 61–65 HRC, delivering excellent wear resistance, high fatigue strength, and stable dimensional accuracy. The retainer is made of polyamide (PA66), lightweight with low friction, ensuring smooth roller guidance and corrosion resistance in general industrial environments.

3. Core Processing Technology (SEO: precision bearing manufacturing, IKO bearing production process): Key processes follow IKO’s strict standards: closed-die forging (dense internal structure), CNC turning (Ra ≤ 0.3μm surface roughness), controlled atmosphere heat treatment (nitrogen-hydrogen atmosphere to avoid oxidation), precision grinding and superfinishing (raceway roughness Ra ≤ 0.04μm). The thrust raceway is precision machined to ensure uniform load distribution, while the PA66 retainer is injection-molded for tight fit with rollers.

4. Service Life (SEO: bearing service life ISO 281, TAF293820 service life): Under standard working conditions (6,000 r/min, axial load 18 kN, proper lubrication, clean environment), the L₁₀ basic rated life (90% reliability) is 26,000 operating hours, calculated in accordance with ISO 281:2007. Key influencing factors: lubrication quality, contamination level, installation alignment, and operating temperature; insufficient lubrication can reduce service life by 35–50%.

5. Application Scenarios and Industries (SEO: thrust needle roller bearing applications, IKO TAF293820 uses): Widely used in automotive transmissions, steering systems, industrial gearboxes, precision machine tools, and small aerospace components. It is suitable for these industries due to its slim design (space-saving), high axial load capacity, and stable performance, adapting to compact, high-precision axial transmission scenarios.

6. Basic Maintenance Requirements (SEO: bearing maintenance guide, IKO bearing lubrication): Maintenance cycle is 1,000–1,200 operating hours. Lubrication: NLGI 2 lithium-based grease, filling 15–25% of bearing free space; re-lubricate every 800–1,000 hours. Cleaning: Clean with clean kerosene; avoid corrosive cleaners. Regular inspection: Check for abnormal noise, temperature rise, and grease leakage; replace lubricant if deteriorated.

7. Installation Precautions (SEO: bearing installation best practices, TAF293820 installation): Pre-installation: Keep area clean, remove burrs from shaft/housing, check fitting surface roughness (Ra ≤ 0.8μm). Installation: Apply thin oil film, press evenly (no tapping), ensure axial alignment tolerance ≤ 0.02 mm. Fastening torque: 6–10 N·m for bearing seat bolts. Post-installation: Rotate manually to check smoothness; normal temperature ≤ 70℃ after 30 minutes. Safety: Wear protective gloves/goggles, use specialized tools to avoid raceway damage.
