Wholesales Excavator Boom Stick/Arm Boss Bush

Boom Stick/Arm Boss Bush components operate under extreme shear stress and dynamic friction during heavy-duty digging operations. Installing precision-engineered bantalan ekskavator at these high-load pivot points effectively absorbs mechanical impact, reducing frame vibration and preventing costly wear on primary linkage structures.

• Pemilihan Material Premium: Our boss bushings are forged and machined from high-strength alloy steel grades, such as 40Cr and 20CrMnTi, ensuring superior yield strength and exceptional resistance against heavy shock loads.

• Perlakuan Panas Lanjutan: Components undergo rigorous carburizing and induction quenching, achieving a deep surface hardness of HRC 58-62 with a hardened depth of 2-5mm for maximum wear resistance.

• Precision CNC Machining: Internal lubrication channels, oil holes, and wall profiles are held to exact tolerances within ±0.01mm, facilitating smooth pin rotation and optimal grease distribution.

By combining deep case-hardening with ultra-precise dimensional tolerances, our bushing bucket ekskavator minimize friction and extend equipment service intervals under harsh job site conditions. These heavy-duty boss bushings feature universal design compatibility across major earthmoving brands, including Komatsu, Caterpillar, Hitachi, Volvo, Kobelco, Doosan, Kubota, Bobcat, Yanmar, Sany, LiuGong, XCMG, and Shantui.

Mengukur Dimensi

Ada tiga informasi utama yang kami perlukan:

• Diameter Pin;
• Jarak antara pusat pin;
• Jarak Telinga ke Telinga (lebar).

LANGKAH 1
Ambil pita pengukur (preferensi kedua) dan/atau jangka sorong (preferensi pertama).
LANGKAH 2
Beralihlah ke bucket atau attachment yang sudah ada yang terpasang dengan baik pada lengan dipper atau pengait cepat ekskavator.
LANGKAH 3
Lakukan pengukuran A, B, C, D, E seakurat mungkin
CATATAN: Dalam kebanyakan kasus A = B, dan C = D, tetapi dalam beberapa kasus mungkin berbeda dan sebaiknya diperiksa ulang.
TIP: Ukuran diameter pin pada umumnya adalah kelipatan 5 mm, biasanya untuk pin adalah 25 mm, 30 mm, 35 mm, dst. Namun, ini tidak selalu terjadi, jadi silakan hubungi kami jika Anda tidak yakin.
