Product Introduction of E345 Bucket Teeth
1. Excavator Bucket Teeth Matching Information
Applicable Models: CAT E345D/E345DL, E349 and E350 series 45-ton excavators, compatible with J550 tooth holder system. OEM part numbers: 9W8552, 1U3552 (standard tooth), 9W8559 (extended sharp tooth), 9W8552RC (rock tooth).
Supporting Parts: Matched with special E345 tooth adapter (6I6464), lock pins and circlips, available in two sizes: 60# and 70# adapter opening.
Single Weight: Standard dirt tooth approx.13.6kg; RC rock tooth 15.7kg; heavy forged mining tooth 18~24.2kg.
2. Digger Bucket Teeth Material & Manufacturing Process
1. Core Material: High chromium-manganese-molybdenum wear-resistant alloy steel with Cr, Mn, Mo additives, featuring hard surface and tough core. Two production processes: precision forging and sand casting; forged teeth deliver superior overall performance.
2. Heat Treatment: Surface quenching hardness HRC48~58 at tooth tip; core impact toughness ≥13J; tensile strength ≥1372MPa; wear-resistant layer depth 6~10mm, outstanding anti-cracking and anti-impact performance against crushed stones.
3. Coating: Standard CAT yellow anti-rust paint or raw black finish; customizable logo stamping available.
3. Four Types & Working Conditions
① Standard Dirt Tooth (9W8552)
Short & robust profile with low digging resistance. Ideal for earthmoving, sand, silt and aggregate loading, widely used in infrastructure grading and river dredging with low wear and high digging efficiency.
② RC Heavy Rock Tooth (9W8552RC)
Reinforced thicker tooth body and tip, mainstream for quarrying. Suitable for granite, bluestone, crushed rock mining and frozen soil breaking, preferred for open pit quarries with over 60% longer service life vs ordinary teeth.
③ Extended Tiger Sharp Tooth (9W8559)
Long tapered tip for superior penetration, applied in ore excavation, shale, coal mining and cobblestone digging for coal mines and tunnel construction.
④ Extra Heavy Reinforced Mining Tooth
Thickened base for heavy impact resistance, designed for open-pit bulk rock handling and massive stone demolition under extreme heavy-load operation.
4. Bucket Teeth Core Advantages
1. Precise Fitting: 3D OEM dimension replication, tight tolerance matching original tooth holders, no wobble during operation and low pin dropout rate; direct replacement without modification.
2. Cost-effective Durability: Forged teeth last 180~260 working hours in mining conditions, far exceeding ordinary carbon steel teeth (50~80 hours), reducing downtime and frequent replacement cost.
3. Self-sharpening Design: Streamlined surface naturally forms sharp cutting edge during abrasion to maintain consistent penetration without manual grinding.
4. Full-condition Selection: Four styles cover earthmoving, rock, coal and construction projects; in-stock supply and custom dimension/hardness for bulk orders.
5. Application Scenarios
Open-pit metal mines, quarrying, civil engineering earthworks, tunnel excavation, river dredging, coal mining, construction waste crushing and aggregate plant loading.
