HRC 40-45 (after heat treatment—balances wear resistance and ductility, avoiding brittle breakage or component scratching)
Core Function
Specialized for separating and pulling bearings from shafts/housings; compatible with cylindrical bearings in automotive, industrial, and agricultural machinery
II. Product Details (PRODUCT DETAILS)
The YEEDA YD55-004/005/006 Bearing Separate Pullers address the core challenges of bearing removal: "component damage, limited size 适配,and fragile tools". With "chromevanadium steel build + size-specific design + rust-resistant finish" as core strengths, each model targets precise user needs for different bearing sizes:
1. Size-Specific Precision: No More "One-Size-Fits-All" Frustration
YD55-004 (30-50mm): Ideal for small bearings in automotive parts (e.g., car wheel hubs, small electric motor shafts). Its compact size allows access to tight spaces (e.g., engine compartments) where larger pullers can’t fit. The 32 PCS/CTN packaging is cost-effective for small repair shops or DIY enthusiasts.
YD55-005 (50-75mm): Designed for medium bearings in agricultural equipment (e.g., tractor gearboxes) or industrial pumps. The balanced weight (31.6kg N.W. per carton) makes it easy to transport between workshop bays, while the 50-75mm range covers most common medium-sized bearings.
YD55-006 (75-105mm): Built for large bearings in heavy machinery (e.g., industrial gearboxes, construction equipment). The forged chromevanadium steel withstands high torque when removing rusted or tightly fitted large bearings, and the 10 PCS/CTN packaging suits large-scale maintenance facilities.
2. Durable Build: Long-Lasting Performance
Chromevanadium Steel Advantage: This material offers 2x the tensile strength of standard carbon steel, ensuring the puller doesn’t bend or snap when applying force to tight bearings. It also resists wear, maintaining precision even after 100+ uses.
Chrome-Plated Surface: Prevents rust and oil buildup—critical for tools used in humid workshops or outdoor agricultural settings. A quick wipe with a dry cloth keeps the puller clean and ready for use.
Heat-Treated Tips: The puller’s contact points (for gripping bearings) are heat-treated to HRC 40-45, ensuring they grip tightly without scratching the bearing or shaft. This avoids costly component damage during removal.
Ergonomic Force Application: The puller’s structure distributes force evenly across the bearing, reducing the effort needed to separate tight fits. This is especially useful for DIY users or technicians performing repeated removals.
III. Application Scenarios (APPLICATION SCENARIOS)
1. Auto Repair Shop (YD55-004)
Scenario Requirement: A car repair shop replaces 25 sets of wheel bearings (35-45mm) weekly. The shop needs a compact, cost-effective puller to access tight wheel hub spaces.
Operation Process:
Setup: Select YD55-004 (30-50mm) for the 35-45mm wheel bearings; position the puller’s jaws around the bearing inner race;
2. Removal: Apply steady force to the puller’s handle—chromevanadium steel jaws grip tightly, separating the bearing from the hub in ~1 minute per wheel;
3. Efficiency: 25 sets of bearings (50 wheels) serviced in ~50 minutes; 32 PCS/CTN ensures the shop has enough pullers for multiple technicians;
4. Protection: Chrome-plated surface resists oil from the wheel hub; heat-treated tips leave no scratches on new bearings.
Scenario Requirement: A farm services 8 tractors (each with 60mm gearbox bearings) monthly. The farm needs a durable puller that works in outdoor, dusty conditions.
Operation Process:
Setup: Use YD55-005 (50-75mm) for the 60mm bearings; clean the puller’s jaws (chrome plating wipes clean easily) before use;
2. Removal: Leverage the puller’s forged structure to loosen rusted bearings—chromevanadium steel withstands high torque without bending;
3. Durability: The puller resists dust and moisture during outdoor use; no rust after monthly exposure to farm conditions;
4. Convenience: 20 PCS/CTN is enough for the farm’s monthly maintenance; the puller’s weight (easy to carry) allows on-site repairs.
Scenario Requirement: A manufacturing plant maintains 10 industrial gearboxes (each with 90mm bearings) quarterly. The plant needs a heavy-duty puller for large, tightly fitted bearings.
Operation Process:
Setup: Deploy YD55-006 (75-105mm) for the 90mm gearbox bearings; check the puller’s jaws for wear (forged steel shows minimal wear after 3+ uses);
2. Removal: Apply force evenly— the puller’s structure distributes pressure to avoid bearing cracking; large bearings are separated in ~3 minutes each;
4. Cost-Saving: 10 PCS/CTN is sufficient for quarterly maintenance; the puller’s long service life avoids frequent replacements.
Effect: Heavy-duty build handles large bearings; even force distribution protects gearboxes; long lifespan cuts costs.
IV. Frequently Asked Questions (FAQ)
Q1: The puller’s jaws slip when removing tight bearings. How to fix this?
A1: Slippage is usually due to improper jaw positioning or worn tips. Solutions: 1) Position Jaws Correctly: Ensure the puller’s jaws grip the bearing’s inner race (not the outer race or seal)—this provides maximum traction; 2) Clean Contact Surfaces: Wipe oil, rust, or dust from the bearing and puller jaws with a cloth—debris reduces grip; 3) Inspect Jaw Tips: If tips are worn (rounded), replace the puller (chromevanadium steel jaws are not repairable once worn).
Q2: Can YD55-006 (75-105mm) be used for bearings smaller than 75mm (e.g., 60mm)?
A2: No. Using a large puller on small bearings will: 1) Cause unstable gripping (jaws can’t fit tightly around the 60mm bearing, leading to slippage); 2) Risk damaging the bearing or shaft (the puller’s large size applies uneven force); 3) Waste effort (the puller is oversize for the task). For 60mm bearings, use YD55-005 (50-75mm).
Q3: The puller has light rust spots. How to remove them and prevent recurrence?
A3: 1) Remove Rust: Wipe rust spots with a wire brush (for light rust) or a cloth dipped in white vinegar (for stubborn spots); rinse with water and dry thoroughly; 2) Prevent Future Rust: Apply a thin layer of machine oil to the chrome-plated surface after use; store the puller in a dry, sealed container (avoid humid workshops or outdoor storage); 3) Regular Maintenance: Inspect the puller monthly—address small rust spots immediately to avoid spreading.
Q4: How to choose the right model for my bearing size?
A4: Match the model to your bearing’s outer diameter: 1) Small Bearings (30-50mm): YD55-004—ideal for auto wheel bearings, small motor bearings; 2) Medium Bearings (50-75mm): YD55-005—suits tractor gearboxes, industrial pumps; 3) Large Bearings (75-105mm): YD55-006—best for heavy machinery gearboxes, construction equipment. Always choose a model where the bearing size falls within the puller’s capacity range (do not use an oversize/undersize puller).
